getting dir(x), but not as list of strings?

[mh at pixar.com]

I want to iterate over members of a module, something like:

    for i in dir(x):
        if type(i) == types.FunctionType: ...

but of course dir() returns a list of strings.  If x is a module,
how can I get the list of its members as their actual types?

Many TIA!
Mark
