So you'd also like us to shorten the names of the builtins and the the 
keywords? Why bother with "def" when we could just use "d", "class" when 
we could just use "c"? Or *does* readability matter to some degree?

But the "with" statement isn't the one that "with" was reserved for in 
the FAQ, which is really talking about the same kind of "with" statement 
that Visual Basic uses: an implied left operand for unary "." operations.
