Well, I'm floored that you find that at all elegant. It's "elegant"
in much the same way using static to mean 12 different things,
depending upon context, is "elegant". Although here it's worse I'd
say because the meaning is so much closer to the other meaning, so the
expectation of matching behavior is greater. But maybe you dig on
that kind of thing. I see it as a necessary evil. Not something to
go strutting around proudly about.
Dat's all I'm gonna say about it though. I've had my fill on this one.
