There's no shortage of new languages. I have no objection at all to
ceating a new C-like language that uses ":=" for assignment and "==" for
equality. It just can't practically be a replacement for C, and it
shouldn't be called "C".

With a parser, or even just a lexer, there shouldn't be any ambiguities.
Just tokenize the source and replace every "=" token with a ":=" token.
This assumes, of course, that "=" is changed to ":=" both for
assignments and for initializers. Compound assignments presumably
wouldn't be affected; "+=" would still be "+=", not "+:=".
There might be some odd corner cases involving the preprocessor.
