OK. I've been working with this for several weeks and am still
impressed. Today I made a change the I'm sure Lex would frown upon: I
made types local to a spec unit, instead of the default global to a
program. This helps me with multiple Front grammars in a single
compiler.


I know there was a good reason to make types global, but I can't
figure it out. I'd love to be able to contact Lex. Anyone have an
email address? (OK, I'll admit I'm hoping he is lurking here, hence
the obscure reference to global types above.)
