It is really missing, just as it is for most programming languages.
Which language(s) do you know that has such a feature?
And why do you consider it so useful that you expect to find
it in Python?

The main place where I could see such a thing being useful
would be in dynamically loaded code but then the usual
approach is to load a dictionary and an 'in' check suffices.

I'm interested in what use you would make of such a thing?
