Subject: Why is local variable created in one branch of if statement available in the other?

I find it hard to understand why this code prints nil  instead of
saying "unknown method or local variable foo":

> cat hmm.rb
def hmm
  if false
    foo = 'quack'
  else
    p foo
  end
end

hmm
> ruby hmm.rb
nil

Thoughts?
