Maybe this is true in Duff's rc (I don't see how or why, actually) but
it certainly isn't true about my lexer. The only serious lexical hacks
are free carets and the treatment of '('. I guess you can also include
the scanning of variable names (which are presumed to be in the
character class [a-zA-Z0-9_*]).
> 1. Promote '=' as if it was a keyword.
Would anyone like to submit a working yacc grammar for this? After playing
with the grammar for a little bit, I didn't find a way to do this for '='.
It's my suspicion that a working grammar that promoted '=' would be very
ugly, but I'd love to be disproved.
