While I like and support the idea, I think that hijacking the "macro"
keyword now will make it very hard to re-design later.  It would be much
better to reuse the "mixin" keyword for this since it's exactly what's
happening: defining a function for mixing in:

mixin max(int a, int b) {...}

It could be problematic from the grammar perspective though.
