It's because Python/Ruby already ships with complex numbers.

So std_complex.i is somewhat inconsistent with the rest of the std_*
stuff, and only defines conversion typemaps to convert between
std::complex< float/double > and Python/Ruby native stuff and not a
class wrapper.

Just try this:

%module stdcomplex
%include std_complex.i

%inline %{
	void func( const std::complex< float >& b )
	{
          fprintf(stderr, "-> %f %f\n", b.real(), b.imag() );
	}
%}

---- from python
from stdcomplex import *

func( complex(2,0) )
-> 2.000000 0.000000


And I also tried it with ruby and found out my code for it is currently
broken :(
Time to add yet another unit test :)
