Does Python really follow its philosophy of "Readability counts"?

Again, there have to be some language extensions to communicate the
necessary info to the external tool.  Python 3.0 begins to do that,
but as others have mentioned, it's still in a formative state while we
get more experience with it.  The other angle is that the compiler can
use static knowledge about the program to make the program run faster,
so if the checks are in an external tool, there has to be
communication in both directions to make use of that.
