I think these numbers are a little misleading because
mandatory whitespace, though an expressive element 
(i.e. the meaning of the program changes if you take 
it out) is not counted as a token. What would the numbers
be if you counted mandatory whitespace?  Here's Scheme's
entry:  

((lambda(x y)(+ x y))3 5)        20 elements
