Way to bind the same variable in different namespace

[ffyu-lj]

Tried to bind in two different modules (which will be imported at the same time):

handle = user::client<ClassA>::handle

and

handle = user::client<ClassB>::handle

Binding code looks like the below:
For module A:

using handleA = user::client<ClassA>::handle;
void bind_handle(py::module &m)
{
    py::class<handleA> pyClass(m, "ClassAhandle");
    pyClass.def("id", &handleA::getId);
}

The binding code looks similar for module B, only replacing 'A' with 'B'.

When I import modules A and B, I got "ImportError: generic_type: type "ClassBhandle" is already registered!"

I just wonder if there is a way to bind the handle, for it to be used in both modules A and B.
Thanks for any ideas.
