Interesting talk on Python vs. Ruby and how he would like Python to have just a bit more syntactic flexibility.

There are non-trivial languages that have been made without procedures
and statements and non-trivial programs written on those languages.
There is technically no need for a lambda that supports statements;
someone could simply write a full-blown Monad framework and all of the
things required for IO Monad and all their syntax sugars up to near a
level of Haskell. Then we can do away with 'def's and all the statements
or make them syntax sugar for the Monads.
Now, why don't we start a PEP to make python a fully-functional language
