Did I learn something from this? You bet. Even though my Latin is extremely rusty, thinking about Perl in terms of a spoken (albeit dead) language gave me a new outlook. Plus it looks cool. I also found that the best way to approach writing in Perligata is not to take regular Perl and try to translate it one line at a time, but to actually think in Perligata. (Your milage may vary, of course.)

Talking of dead languages, reading your Perligata program reminded me of COBOL. It has much in common, in particular the longwindedness with which one needs to spell matters out to achieve the simplest of tasks.

I wonder if there's scope for a Latin to COBOL source filter :).
