// habits have a structure such that they contain information about their positional
// arguments.  they are made with a macro that turns the args into local variables.
// the function to call them takes any number of arguments, and these are placed in the
// thread context according to the information in the habit.

// idea: preprocessor for level3 runs with habits
// runs after C preprocessor and responds to output produced by macros e.g.
// SET SYMBOL: <any string>
// UNSET SYMBOL: <any string>
// between the two <any string> is converted to valid c symbol when not double quoted.
// removes much of the need for individual word declarations,
// 	and starts to pave way towards user/intellect participation
// here, could remove the 'tok' for local refnames.
