[Zope-Coders] -O considered useful

[Jeremy Hylton]

This reminds me:

If you run with python -O, you execute slightly different code.  The
compiler optimizes away all code inside if __debug__ and all code in
assert statements.  As a result, many regression tests do nothing when
run with python -O.

We should fix our tests to use the assertXXX methods, like assertEqual
instead of using assert statements.  Note that assertEqual also
produces a better default error message than assert x == y.
