Quoting myself from a few weeks back:
"""
Random programming thought of the day: "check" is generally a terrible
word in a function name.
Checking stuff is great, but what do you expect to happen if the check
passes/fails? Do you expect the function to return on fail, or throw an
exception? Or just log about it? If you return a value, what should the
return value mean? It's hard to know without looking it up.
Prefer predicates instead, is_stuff_okay() is better than
check_stuff(). Or assert_stuff() if you don't return on failures.

BR,
Jani.
