here's what I wound up doing (in weblib/__init__.py)

#################

def Request():
    import Request, weblib
    weblib.Request = Request.Request
    return Request.Request()

##################

So, the first time I call it I'm really calling a function that calls
a constructor and returns the new object.. and the second time, I call
the constructor directly.

Cheers,
