The solution is to create some function that will create an alias from
an instantiation
of std container. Obviously Py++ does if for you, but the names it
creates are very long
and ugly. You can do something better.

Take a look on container traits classes: http://tinyurl.com/yeezdc .
These classes will
help you to extract value_type( mapped_type ) from the container.
( source code: http://tinyurl.com/yeco7e )

Use pygccxml.declaration.all_container_traits variable. It defines a list of all
container traits classes

Now the code is pretty trivial:

def find_out_container_traits( cls ):
    for ct in pygccxml.declaration.all_container_traits:
        if ct.is_my_case( cls ):
            return ct
    else:
        return None

def mangle( cls, ct ):
    element_type = ct.element_type( cls )
    cls.rename( .... )

mb = module_builder_t( ... )
for cls in mb.classes():
    ct = find_out_container_traits( cls )
    if ct:
        mangle( cls, ct )

This should work.

I think that the reason is that too many different typedefs for the
instantiation

Is this the right direction?
