Returning references from C++

[xemjeff]

I am able to return pointers to objects from C++ through dukglue, but I can't seem to return references:

//this function registers and works fine
// m_position is type Vector3

Vector3* Robot::pos()
{
    return &m_position;
}

//this fails to compile if I try to register
Vector3& Robot::position()
{
    return m_position;
}

I register like this:

	dukglue_register_method(ctx, &Robot::position, "position")

and get these compile errors (below), which seems to indicate that references for my Vector3 class are not supported.

../include/dukglue/register_class.h:113:53:   required from ‘void dukglue_register_method(duk_context*, RetType (Cls::*)(Ts ...), const char*) [with Cls = Robot; RetType = Vector3&; Ts = {}; duk_context = duk_hthread]’

dukglue/tests/test_robot.cpp:21:59:   required from here

dukglue/tests/../include/dukglue/detail_method.h:129:67: error: no matching function for call to ‘dukglue::types::DukType<Vector3>::push<Vector3&>(duk_context*&, std::remove_reference<Vector3&>::type)’
      DukType<typename Bare<RetType>::type>::template push<RetType>(ctx, std::move(return_val));

Is this a bug, a limitation of dukglue, or am I just not registering correctly?

Thanks.
