testing for a class having been loaded

[Alan Snyder]

All questions are worthy of some study, but I’m not getting why you question the sanity of asking for the status of classes but have no problem with asking for the status of packages.

Do you have some vague sense of possible problems?

To be honest, the scenario is a bit odd, there must be a saner solution that doesn't involve checking if classes are loaded.
