Programming languages and spoken ones have a different way of changing. In spoken languages, people just speak differently as time goes by, and after some decades or centuries, thing that would have been "errors" are then accepted to be correct usage. Whereas programming languages need to be changed (i.e. get a different compiler/interpreter) in order to accept "errors" as a correct input.

I was never really fascinated by Esperanto, I'd rather have something like "simplified English" as an official international language. Common people in India prove that it's possible to simplify the English grammar radically and still be understood.

About Perl, I like its flexibility. That makes it much easier to code than other languages. A good thing about perl are its warnings and error messages, they're quite smart sometimes. Quite unlike, for example, JavaScript where most of the times the interpreter only states something like "you made an error somewhere in this document".
