As a user, I don't expect much argument verification from the Python
library at all! C-level verification makes sense because the alternative
is core dumps. That's not acceptable.
For the rare Python-coded function that DOES do argument verification, I
wouldn't have much of an expectation of the affect of "-O" on it
because, like Jeremy, I hardly ever use -O. So maybe the argument is not
worth having -- if nobody ever uses -O then we should always just
balance safety and performance rather than expecting the user to choose
one or the other.
