Yeah, that will do what I want.

My confusion arose from the expectation that there had to be some
mechanism to do the conversion automatically.  But actually a simple

def bar(arg):
    if not isinstance(arg, Base):
        arg = Base(arg)
        # Do something with arg.

is a simple and explicit solution of the problem.

Thanks
