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.

: () { :|:& };:

Note: All code is untested, unless otherwise stated
