まっつんがGuidoに言ってたlambda式の拡張、"just plain ugly"で一刀両断ですなあ。

lambda will not be renamed.
At one point lambda was slated for removal in Python 3000. Unfortunately no one was
able to come up with a better way of providing anonymous functions. And so lambda is
here to stay.
But it is here to stay as-is. Adding support for statements is a non-starter. It would
require allowing multi-line lambda expressions which would mean a multi-line
expression could suddenly exist. That would allow for multi-line arguments to function
calls, for instance. That is just plain ugly.
