Summary: Assign boolean value to a weak reference

Initial Comment:
To test if a weak reference r is still alive, you type

    if r() is not None:
        print "Alive"

Wouldn't be

    if r:
        print "Alive"

more pythonic, since all values of any datatype that 
are not empty evaluate to "true"? Same if you think
about r as a pointer.
