What are the differences between Ruby's blocks and Python's lambdas?

The main one is that a Python lambda can only contain
an expression, whereas a Ruby block can contain arbitrary
statements.

If that restriction were lifted one day (discussions
come up periodically about doing that somehow) there
would remain another difference -- in Python, names
cannot be rebound in a lexically enclosing local
scope.
