Assertions that you need in production should be written as
proper if-statements.

I know some people will disagree, but IMO using "assert" is the wrong
approach in such situations - it's meant for development and testing
only, not as short-cut to avoid having to write a proper error
handler :-)

If they were, Python would not drop creating code for them when
using Python in production -O mode.
