in reply to Perl and Linguistics
This question reminded me of something, and after a few days of not remembering what, I've got it. Graham Nelson, a mathematician, designed a small-ish language for writing games with a mind towards "natural language" principles, and he was nice enough to write an article analyzing the language in those terms.
It's not directly about Perl - I don't think Perl is even mentioned - but the idea is on target and the bibliography might help you.
