My real problems listing is stuff that in an ideal world would never be discovered after the fact, but in the real world frequently is.

As for your whoa, you read correctly. If I am setting up a hash with 100 elements that I expect to access a million times, the cost of returning it as a list may indeed be outweighed by the fact of looking up that reference a million times.

Continuing on, garbage collector? What garbage collector? You didn't know that Perl has no garbage collector? It uses reference counting, and if you create circular references, that is your problem. Oh, and last I heard the only OS under which Perl actually returns memory to the OS is the Macintosh.

As for the benchmarks, you are talking to the wrong guy if you expect me to care. I routinely put in run-time checks that get called every time my function runs and verify that the argument list really did make sense. This makes my code easier to develop, and for what I do debugging time is worth more than computer time.

If you really care about performance, Perl is the wrong language. It is fast for an interpreted language, sure, but compared to C it is pathetic. I mean, in C you don't waste time doing such silly things as worrying about whether or not your string is too large and needs to be moved to somewhere it has more room, no you just let them quickly overflow that buffer!

Really, my opinion on optimizing is that it is like running. If you are so eager to run that you start flailing your feet, you will fall over. First make sure you are upright and moving...
