Two points:

(1) There's no reason to get uncomfortable even if they're removed. 
You'd just replace [] with list().

(2) *IMPORTANT* If this happens *at all*, it won't happen until Python 
3.0, which is probably at least 5 years away.  And the Python 2.X branch 
will still be available then, so if you don't like Python 3.0, you don't 
have to use it.
