Is it really worth changing a well-established language syntax, in such a
way that would break the hell out of existing programs, in order to conform
with what is admittedly the dominant notation?  I think leaving C alone to
keep from breaking existing programs and programmers is worth the confusion
it may cause to some people.

Unless you advertise the language accepted by this preprocessor as a
language which is similar to C, but is NOT C, I sincerely doubt that.  I
find that the fake ALGOL 68 crap that Steve Bourne used to write the Bourne
shell and "adb" to make the code a lot *less* readable.  Let C be C!
