This optimises the case where a Python function is, for example, stored to a JavaScript attribute and then later retrieved from Python. The Python function no longer needs to be a proxy with double proxying needed for the call from Python -> JavaScript -> Python. Signed-off-by: Damien George <damien@micropython.org>
