Assigning lambda functions to names generally shouldn't be done. Just
use def. You're asking for another way to do a bad thing that has a
better alternative.

There have periodically been proposals for the opposite, which would
take care of some of the alternatives:

def op["double"](x): return x * x

This kind of proposal has its own issues, but I think it has a much
better chance of being accepted than a way of creating and assigning
lambda functions.
