So I tried it (with Deparse)...

while ()  { $_++; last if $_ == 1000; }
while (1) { $_++; last if $_ == 1000; }
for (;;)  { $_++; last if $_ == 1000; }

[download]
perl -MO=Deparse test.pl
for (;;) {
    ++$_;
    last if $_ == 1000;
}
for (;;) {
    ++$_;
    last if $_ == 1000;
}
for (;;) {
    ++$_;
    last if $_ == 1000;
}
test.pl syntax OK

So they should be all the same speed. I'm with tye on this one - I'll be sticking with with while(1) since I think it looks nicer.

Have fun,
