I know it's *going* away, but it hasn't *gone* away yet.
Personally I'm glad this is going away. I'm not bothered by the caveats of the docs: it's the construct itself that somehow strikes me as "innatural", to the point that I've never been bitten in the neck by using it inadvertently for I would have never ever though about doing so...
In fact a declaration is fundamentally a way to introduce an "object" to be used subsequently, and the fact that it can be used also in the same statement in which it is declared doesn't make things really different. So how can I *declare* something depending on a condition?!? I can branch over a condition to execute either one block or another *within* which things can be declared or some such. Not the other way round...

A question out of curiousity: who is this Green of Green's functions? Is he the same person of Green's theorem? :)
Yes. He was also an early environmentalist; hence the current phrases "green" this and "green" that... - David C. Ullrich on sci.math, thread "Who is Green?"
