string to function reference

Hi,


I've got a string holding a name of the function in the same module:


def foo():
    print "I'm foo"

s = "foo"


The question is, how do I call the function foo given its name as a
string. The three approaches I could see are:

1) exec, as in:

exec s + "()"


2) globals(), as in:

(globals()[ s ])()


3) __dict__, which is no better than globals().


All of these approaches are simply waay too ugly, imvho. Does anyone
see a simpler/cleaner/more elegant way of achieving this.
