What should be done here? Remove this code or print class names?

I remember for 2.1 it made sense to print out instances because very few mod authors will actually be using them (I don't have specifics but I believe the number of mods using instances, not static calls, is still small).

But even if the number of mods using instances increases, it makes sense to have that info while debugging, perhaps we could expand that a little bit by also including static calls and plain functions as well.
