Summary: SWIG does not detect reference type

Initial Comment:
Hello,
When I run SWIG on my source code, it generates invalid code, because I have hidden a reference type in a struct member:
template <typename TYPE> 
    struct ReturnType {
      typedef const TYPE& ConstValue;
      typedef TYPE& Value;
    };

Swig generates 
tlp::ReturnType< tlp::PointType::RealType >::ConstValue result;
when wrapping a function returning a ReturnType<...>::ConstValue and gcc complains this is a reference type and it's not initialized.

Hope this is not an impossible feature to implement :)
