An anecdote of my career is that some programming languages attract different kinds of programmers. I've dealt with Delphi in the beginning of my career and while there was nothing wrong with the language, it seemed to attract a lot of bad programmers writing really poor code.

And Perl was the opposite of this anecdote: the most brilliant engineers I've met in my career were Perl monks, as they would call themselves. I respect Perl for that :)
