	// 			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)
