again, no, since sort does not behave that way currently.
however, if it did, then this would be a very common error. how do you
force void context currently? and list context? it's possible, of course,
but it's extreme action at-a-distance.

it's similar, yes, and only being able to iterate once over a hash even
in totally different modules by different authors is an extremely nasty
thing, even if it occurs rarely in practise (it bite me about three times
in the last 6 years)

what are you talking about (what range operators have been added to "later
perls"?). if you mean ".." (which is very old) then I can't follow you: ..
became smarter but did not change semantics.

The real problem is the lack of optimization in this part of perl, not yet
another weird semantics that breaks at a distance ;)
I'd still liek the huh? operator (??) in perl, though ;)

It looks like a bug to me ;)
