It's functional in the sense that you only assign once to a variable. 
It's not functional in the sense that calling "read" on the same file 
twice (in any language) can give you different results. Erlang just has 
lots more of that latter kind of non-functionalism.

But yeah, you have to pass the seed to the random number generator, and 
it gives you back your random number and a new seed to remember for 
later. :-)

How does Haskell handle things like the function for "the time right now"?
