// PLAN HERE: use EXPRESSIONS that effectively evaluate to FIRST-STEP,LAST-STEPS PAIRS
// to implement SCRIPTING SYSTEM with THREE MAJOR PARSING TYPES:
// functions ["when"]
// step blocks ["[" "]"]
// conditions ["?" or "pick" or "cond[ition"] could be made function-like
//
// LABELS and STRINGS are handled specially.

// look slike symbols must be processed before use.  is a litle confusing.
// local context must be tracked, not too hard assuming everything is assigned before being
// used.
// 	given we are tracking the function context, we can figure out whether a symbol refers
// 	to it.  if it doesn't, it must refer to an outer context.  atm we have 1 outer context,
// 	has names.  miht as well give the file a name context or something.  for now we can use
// 	the global context if not in the set.
//
// 		this means every [] needs a way to find the function context and update it.
//
// 	assign-info [= make-concept ] size tiny

// uhh confused around difference between literal strings and contextual names
// 	when yuo put "" around something, it puts it into the list of known literals for
// 	the step to use.  when you don't, it puts it into the map of things to get from the context.
// 	it is stored as a literal string either way.

// the conflict around literal strings was resolved for karl by him realizing that in this code,
// there is no need to rewire the insides of the referenced concepts.
// they are used only by reference.  so literal strings make the most sense.

// we'll need a way to pick concepts used for local-context references
// they have string names here.
// there should be no problem with using actual string objects to do this.
// but we would need a global database of string objects so that we're referring to the same
// object all the time.  i began the process of switching the name system to use a generalized
// global database like this, but didn't value pursuing it.
// we can use these string objects quickly by looking for named concepts and using their names
// instead of them.  is a hack, but makes the inner structure that may have been requested.

// make parser.  2nd line is name resolver for globals.
// reads lines starting with 'when'.  stream is ref.  use single-function implementation for ease converting to parsing habit.  worries about storing data resolved by parsing generality.  parse better in level3 if appropriate.
// 	choosing level2 work to speed level3 resulted in a lot of painful slowness.
// 	not sure why.
// 	maybe levels relate to expected thought associations and planning.

// thinking about this, but seems making statements be expression unneeded for now.
// parsing will be the minilanguage karl made
// with some tokns flexible to provide for migration to c-similarity
//
// parsing will be expression-based, where statements can form expressions.
// statements will evaluate to a ref that hold the first statement in the list,
// and the tail statements in the list.
// 'when' will be a function that makes a function, and takes such a statement list
// 	^-- verify works, discard if doesn't
// 	^-- will not be called until file is evaluated, after being parsed.
// 	file evaluates to statement list.
// 'pick' will be a function that takes an arbitrary number of statements.  it will be the only one to do so and this feature will be hard-coded.
// 	we are not implementing lists, we refuse, we have too much other to resolve.
//  
//  so, what the sysem does is parse statement lists.
//  = makes new concepts exist in a local context.
//  since 'when' uses global values, habits are accessible.
//
//  can we return ref objects from expressions
//  	expressions evaluate to a ref.
//  	only when accepts statement lists.
//  		how are labels used in cond
//  	labels produce refs in local context?
//  		labels are values local to parsing
//  		= are values local to running

	// 		auxiliary files, can propose to rewrite main file?
	// 			good enough for now.
	// 	additional unresolved concern: want whole file parseable as a script
	// 		okay the outer command is 'when dump concept [ ... ]'
	// 		i guess that means we want [] to make a lot of symbols into 1 symbol.
	// 		then when is a function that takes 3 symbols
	// 			no, when was defined differently.
	// 			instead we would do when dump [ concept ] [ ... ]
	// 			because could be n args
	// 		oh.  that looks okay, though.
	// 		how about file is made of commands that do parsing.
	// 		'when' then spawns a parser named 'when'.  it can process stream however
	// 		it desires.
	// 			then deserializers, desummarizers need to parse streams
	// 			want summarized data without streams, internally?
	// 				ummm wouldn't worry about it
	// 	propose file is made of lists of symbols, a little
	// 	[ when dump concept [ ... ] ] [ etc ]
	// 	[when dump concept [...]] [etc]
	//		generalization is valued ...
	//	i like the list approach.
	//	comments can be treated special
	//	nah comments can become [comment free-text]
	//		so we partly propose implementing lisp with brackets
	//		to speed typing , removes shift key
	//	functions get list of symbols passed, and string rep of all for comment preservation
	//	
	// 	binary form likely resolves concern.
	// 		proposal will be that habit can replace if it will always be able to
	// 		reproduce.
	// ]
	//
	// internal structure could be simple too.
	// 	hmm want tags.  okay, so arguments are objects?
	// 		since things are ternary, we could use the link 'type' to store data
	// 		oh huh
	// 		so, 'first-step' is special, but everything else is an arg.
	// 		no, this is what karl's 'is' is for.  you make the type store extra data, but if it 'is' an arg,
	// 		or 'is' something that is an arg, it counts as an arg.
	// 		he wanted to implement a way to lookup types by eveyrthing something is, which is easy to do by
	// 		adding an index of categories to level-0.
	// 		or the system could do it later.
	//
	// so, if oyu want to rewrite steplists, maybe [arg->arg1 arg->arg2 arg->arg3 first->[action->action arg1->source arg2->source arg3->`source]
	// 	propose using strings to indicate information, rather than node structure.
	//		this will make a contextual index of word meaning
	//		`source doesn't refer to a unique concept.  it means you can only refer to things with names.
	//			everything has a name inside this kind of habit.
	//			i suppose ...
	//
	//   	how scripts look.  instead of while/if, are doing 'condition'
	//   	influences imply above block is preferred.  was leaning towards c++ code as below, takes longer
	//
	// ref name(ref arg1, ref arg2, ref arg3)
	// {
	// 	while() {}
	// 	if() {}
	// }
	//
	// takes a lot more parsing work, but should be okay
