I am mostly suggesting Perl vs. Perl cmpthese benchmarks, which tell you how one WTDI performs compares to another, usually regardless of what platform you are running on.

The idea is that for most common tasks, operations, algorithms, etc., we will have a vast and open body of organized knowledge that usually provides:

• A fast WTDI
• An elegant and perlish WTDI
• An obvious WTDI
• A contorted and masochist WTDI
• A just plain wrong WTDI

Of course, these are not always mutually exclusive :)
