I've always asked myself:
"Why would anyone using Scheme want to parse anything
but s-expressions?"

Well, now I know.

Does anyone have Scheme versions of Lex and/or Yacc
written in Scheme? I'll probably be using Scheme->C. Are they
available for ftp and how reliable/complete are they
relative to the Sun C versions. Are there
any papers on this? What about performance?

Specifically, I'm trying to parse HyperTalk. Are their
any public domain parsers/grammars for it?
