A while ago, I created a LALR(1) grammar with "generic" symbols that
encapsulated essentially all "standard" syntactic constructs I've seen
in programming languages: top-level forms, statements, blocks,
sequences, constructors, keyword forms (including ones with op,
l-values, r-values, prefix/postfix/infix & unary/binary operators,
calls, destructuring l-values, quoted data, interpolating quotation
and other interpolating forms, etc. It was pretty neat. If I can
ensure it (or some equivalent grammar) is unencumbered I'd like to
document it and extend emacs's syntax tables to be able to analyze a
buffer using these constructs instead of just s-expressions, with
modes just providing a map of language-specific tokens to the generic
symbols.
