This might sound silly, but how about if D stopped allowing 0..2  as a

Fixing it en masse would be pretty trivial... just run a regex to replace
     "\b(\d+)\.\."
with
     "\1 .. "
and you're good to go.

(Or if you want more accuracy, just take the compiler output and feed it
back with a fix -- that would work too.)

The benefit, though, is that now you can do maximal munch without
worrying about this edge case... which sure makes it easier to make a
lexer.

Thoughts?

... why is this even done at the lexical stage? It should be done at the parsing stage if anything.
