	It's not needed if all I were doing were walking the AST and
	compiling.  Hence, it's not needed in the "pure" sense.  It's
	only needed by the pesky GUI folks to draw pretty red
	squiggles.  (Real programmers don't need no stinking red
	squiggles!)  I don't like the idea of keeping around extra
	stuff so that all potential users of the AST have to deal with
	it.

	Whoops!  Sorry, Terence.  (Is there a variant with to 'r's?)

	Yeah, yeah.  Sigh...  :-(
