A lexical change (a breaking change, but trivial to fix)

[Mehrdad]

This might sound silly, but how about if D stopped allowing   
0..2  as a range, and instead just said "invalid floating-point 
number"?

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?
