Indeed it isn't.  However, one of the nice properties of types is that 
they can always become stronger and more expressive.  One of the 
problems in doing it though is agreeing in which ways to make them 
stronger.  After all, with sufficiently strong types one can describe 
pretty much any property one wishes.
