Well, there's a whole bunch of them at Ericsson use erlide, plus
others that I only have fragmentary information. Of course, I believe
that an IDE helps the development process, but I know that it is a
controversial question. Some people like it, some don't.

Yes, that would be good enough for me -- but as a generic tool
provider, I can't force people to follow any rules. There is also the
issue of legacy code, that nobody will touch as long as it works.

Anyway, the simple usage you describe above doesn't require a
preprocessor, these could be handled inside the language with some
additions to the compiler. This would enforce the cleanliness and I
don't think anybody would feel sorry about that. For the dirty work,
the preprocessor could still be there, if needed.
