You're correct - that was the actual question. The question presupposes an incorrect analysis of whatever problem he's attempting to solve. I could've given him an answer to his problem (cause this is a do-able thing), but he would not have grown as a programmer. The analysis of the problem was wrong. Ultimately, that is a goal of PerlMonks. (At least, that's how I've come to see this community.)
We are the carpenters and bricklayers of the Information Age.
Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
Please remember that I'm crufty and crochety. All opinions are purely mine and all code is untested, unless otherwise specified.
