before getting any more serious, i think it is time to move on from sexp-grammar to an actual R⁷RS parser and printer. we're going to be using megaparsec and prettyprinter to read/write R⁷RS S-expressions, and continue to use invertible-grammars for parsing S-expressions into ASTs. this means reimplementing much of sexp-grammar's API.
