I don't know. I suppose that depends on how you define 'bad'! For me,
it is often inconvenient, because I'd prefer to use Pytho
hat, you can't effectively prevent this type of error.
Luckily, I find that they don't actually arise in practice, and I've
spent orders of magnitude more time in C++ having to coerce objects
from one type to another to comply with the static typing than I
probably ever will spend debugging
philosophy and Python's differs from that of (for

produce better results than Java in other circumstances.

Typically you run PHP as a module in your webserver, so there should be
no process startup overhead. mod_python provides the same sort of
