I like Java, too, but how many people are familiar with all the pertinent
Java package classes associated with the problem-of-the-moment? (Why, for
example, was Tree in one of the UI packages [version 1.1]?). The scope of
packages adds to the complexity of understanding how to effectively use
them. MFC is worse, mind you, in terms of its design (and I have not
personally delved into .NET, but OMG). Size does affect complexity, but
yeah, it's not the only measure.

But can you write an accurage clone() method? :-) Well, maybe *you* can...

I have a saying:

	For every complicated problem, there are a bunch of simpler problems
screaming to get out.

If the task is that monolithic, break it up and address bits of it at a
time. I think there's a lot of specs that address too much at once, due to
the geek desire to be 'complete'. I say to heck with complete: give us
something simple first, then layer complexity on top of it. There's people
screaming for XQUERY update support right now, but is everyone who uses
XQUERY going to do updates? (BTW, where in the definition of 'query' does
the term 'update' show up?)

Uh, oh... I've entered the Ranting Zone. Do-do do-do, do-do do-do...
