Well, working is one thing, but it was getting a bit over-sized for its britches and it wasn't in a form I wanted to enhance it in. I expect the lines / functionality ratio will go down eventually. :-) It's also a learning/educational thing.

Like somehow I don't quite yet see how OO is supported in perl. Is the machinery to trace my back my ancestor namespaces in the perl binary or some perl code? Shouldn't it just look in the "handler (key or timer handler) routine's namespace for an @ISA? Then "it" (whatever it is), follows the package list depth-first, left-to-right? Yes? (or no...) But that sequencing doesn't seem to explain why it's not "properly" searching parent class (package) for matches after the current package when called from Tk in a callback function.
