Maybe, but first you should do static type inference as much as you can, 
see

http://www.python.org/pycon/dc2004/papers/1/paper.pdf

and if you then want to give hints there is no need to extend the 
syntax; simply add a private method on Module for attaching type hints 
to methods etc. I think the StarKiller has some kind of type annotation 
language like that.
But speed may not be very important anyway... ;)
