string to function reference

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