Actually, I think my problem relates to lambda functions, not to the Menu per 
se. For example, at the interactive prompt, I can type:

a = lambda: sys.exit()

But not:

a = lambda: pass

I wanted a lambda function that was equivalent to:

def doNothing():
   pass

Why doesn't python let me do that?
