Re: [Boost-users] [proto] learning proto slowly, a small (math)complex library

try

std::complex<double> z = 4. + 5.i;

ok, I put that but still doesn't work.

Incidentally, you should have a real transform able to turn any complex_expression into a complex and not rely on a given fixed AST structure.

What if i do z = i + i + 3 + 4*i ?

I know, but I want to keep it simple, std::complex<double> z = 4. + 5.*i; will be just a glorified constructor.
