Moving the kernel to modern C

In all the programming languages under discussion, 3 + 1 returns 4. In mathematics, a + b is an arbitrary function, almost always associative and commutative; 3 + 1 can equal 0, in Z mod 4. I've certainly seen + used as a concatenation operator in real life, like in rebuses.

It's a signal that you should look it up and that it might evaluate your arguments more than once, for example.

Non-hygenic macros are insane. Had you said

I wouldn't have disagreed. So why the difference? Why can developers be trusted with macros and not operator overloading?
