in reply to An observation on join

If you were developing the Perl programming language, how would you write a join() function that works with a regex as separator? What would it do?

I find that it is often helpful to imagine myself being in a different role, looking at a problem from a different perspective.

    Hey Thanks! That's much better a way to understand that than having to memorize a rule from perldoc.

    Well put! I never bothered thinking about it, but that makes perfect sense. Using a regex for a join would be like saying "get me a food".
