You're saying it _can_ be done in Python? They must have added
something to the standard library again. I mean how can you return
twice a value without a twice function to start with? I've tried.
You'd think
def twice(n):
 return twice(n)
would work, but I get this really long error message.

That would be cruel. I mean the guy has enough problems already...
