Well, that's true. You could theoretically compute something like the weather forecasts on a C-64, but you'd have to wait a few millennia to get the "forecast".

Still, the original concept that you presented was that Perl could do anything any other programming language could do, which is true - but as you point out, it doesn't mean it's feasible. In particular, things that are very time-sensitive may require C or assembly language programming, that sort of thing.

Nevertheless, I do like your idea, because it emphasizes that Perl is quite capable of handling most of the problems that get thrown at it, despite what some people say about it being a "scripting" language, or being "weakly typed", and all that. Hey, it's useful, it's easy to get into it, and it can be fun. What more do you want? Other than a DWIM, I mean...
