I know I'm over a year late, but this application just came up in some consulting work. I believe it to be a GOOD idea to have a utility (or pre-processor) that accepts Perl keywords in Spanish. Anything that HELPS an inner-city Hispanic kid learn about computer programming is a Very Good Thing, indeed. The goal is to learn how to think algorithmically, not struggle with the English language (what's "croak" in Spanish? Please do not give me the word for "die" ...).
I disagree with the argument that it is a "waste of time" for the kids, and an "equivalent to teaching Pascal", which they will never use in the "real world" (BTW, where IS that place?). I learned Pascal very early on, never used it professionally (PL/1 was the closest), but I am thankful of the Pascal experience (Damian Conway did an excellent webcast on this subject and Perl6). In fact, I wish that there never WAS a working Pascal compiler, but that the language concept was taught in school nevertheless.
My German friends use English reserved words, but German variable names and comments. So why not have a translator that converts the entire Perl script (but I'd be happy with just the reserved words and Standard Library names)?
Since I have never written a parser, and have limited experience in Spanish, I searched for such a thing, but only found sources for Perl language TRAINING in foreign languages. I'm new around here, so I might have overlooked something. Does anyone know of such a thing?
