Having said that in the time ive been using perl I think ive needed the construct a mere handful of times.
To reinforce the point.. I've literally never used it. There was not a single instance I wasn't equally or better served with the other constructs.
And to be honest, considering the number of cases I advised people not to use for(;;) for whatever they were using it for, and the number of times I restructured loops in others' code to not use it, if it was to disappear from the language I wouldn't shed a tear. Actually, scratch that, I'd be cheering.
