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

In classic Pascal, a procedure was distinct from a function in that it had  
no return value.  The concept doesn't really apply in Python; there are no  
procedures in that sense, since if a function terminates without supplying  
an explicit return value it returns None.
