I have a loop where I'd like have something happening between each loop interation, but not after the last iteration. This can be done with some kind of sempahor variable, e.g.: 
$count = 2;
foreach (0..2) {} continue {print $_,"\n" if $count--}

Where $count is acting as a sempaphore.

I'm wondering if there is some way to do this without the semaphore. For example, is there some CPAN module that implements a thing like continue that doesn't fire off after the last loop iteration? Or maybe some algorithmic trick I haven't though of. This needs to work with a foreach where I'm not keeping any explicit loop counter (unlike the baby example above).
