I'm pretty sure I said something like "forget what I think, look at what everyone else does." :)
Hard not to think of a dictionary as anything but a set of associations, but I'm quite sure there are perfectly practical reasons for the existing thingie.
Has anybody tried that test out? On stupid phone again...
Anyway I don't think we should worry about what we call the superclass unless it affects compat with some wanted code. Even then, a little shim in the compat package could make up for the difference, no?
