in thread It's a dog, but what kind? (polymorphism , in Perl OO)

The only problem with require in this case is that if you use a variable for the module name, you have to specify the path to the module, not the bare name. Using eval STRING is the accepted idiom around this problem. Yes, it is slow, but it's probably minimal unless you're doing it in a tight loop. In this example, the error handling aspects of eval are a non-factor, since we're just dieing with the error message anyway. Of course, your own code may or may not do that.

[robby_dobby]: marto: yeah, I'd eventually visit Glasgow some day - just to visit the home town of GHC :-)
[robby_dobby]: Corion: Oh, that's awesome! Your timing is perfect enough to see all hell break loose when you get back at work :P
[marto]: well, let me know in advance, I'll buy you a pint :)
[Corion]: robby_dobby: No, I'm returning in the second workweek of January. The main hectic parts are in the first days after the start of the new year
[robby_dobby]: marto: and, I'm not sure I'd be around here long enough for YAPC::EU
[marto]: Corion nice, what are you plans for Christmas?
[robby_dobby]: Corion: Nice, you just won't be around to deal with the mess - enjoy your vacation :-)
[robby_dobby]: marto: Sure, will do. Thanks!
[Corion]: marto: No great plans - I'll meet with my sister, my brother and my mother, but that's all :)
[Corion]: ... and also a visit to my godson+family of course :)
