I didn't write that, Guido did.  I agree with you, and others who have 
made the same point you made.  I would have to think Guido is already 
aware of this issue (keep python simple).  I'm not sure what his 
motivations are for wanting to add static typing to python, not that I'm 
against it.

It doesn't matter a whole lot either way since Python 3000 is still 
years away and you can already do static typing now with Pyrex or boo, 
as well as many other things that people have requested for python from 
little things like ++i to bigger features like multi-line anonymous 
methods/closures.
