Ruby

@nobu (Nobuyoshi Nakada): i don't know if that would be better, but can the parser be changed to support that stuff like "2+1i" would create the Complex object directly?

Actually, currently, there is no literal for complex numbers whose real part is non-zero. I think we need a literal to cover such cases. If something along nobu's suggestion works, that would be preferable.

it wasn't a suggestion from him, i just wanted to ping him so he can see the message

There would be a chance to optimize such expressions, but it is not a single literal syntactically, and constant folding is disabled in Ruby for its dynamic nature.
New literal syntax will be needed for an (impurely) imaginary number literal, but I doubt that we really need it.
