Well, I asked, because you have to #include <typeinfo> before you can 
use std::type_info, which is rather more built-in than std::complex in 
most compilers.

However, I've always thought that restriction somewhat lame. :-)

I agree that this could be made to work, by essentially hard-wiring 
std::complex/_Complex into the compiler, rather than defining it in the 
library.

That would be a considerably more radical change, though; historically, 
G++ has indeed treated the types as separate.
