Having taught a course in Perl for a couple of years at school, I was consistenly amazed at the number of weirdly thought out programming ideas that my students came up with. For example, I once had a student who wanted some help thinking out a programming assignment. The task was to write a subroutine that took a 3-letter sequence of DNA, and translate that into the corresponding amino acid sequence. I gave it as an exercise in using hashes (which I had just lectured on that week). Basically, the student wanted to use two arrays of DNA and amino acids as an associative array, so that to translate AAA to amino acids, you would look up the array position of the AAA element in the DNA array, and then find the amino acid at the corresponding position in the amino acid array. To me, this is a perfect example of a "way to do it" that shouldn't be used, because:

A quick re-hash (hah!) of the lesson on hashes set the student on the right path.

Anyways, wrongness is in the eye of the beholder, but I think that it's a good idea for a programming language community (whether it be a work environment, a course, or a site like PerlMonks) to recommend and enforce some sense of quality in programming.

I wouldn't cite C or C++ as hallmarks of programmer discipline either. I've seen some stuff with pointers that would make my CS professors absolutely cringe. :)
