I think of this like spoken languages. Sure English is great. We know it cold, it's the offical language in North America (US&CAN) and the European Union. But even within those regions, there's advantage to speaking other language. It allows you to move comfertably from one situation to the next.

Using only Perl would allow you to do just about anything. But as Fastole and jcwren mention, sometimes you need another language that better fits a situtation. Here in Canada, French and English are offical languages, and when I took a trip to Montreal, I brought along a French/English dictionary so I could be better equiped to deal with anything that came up.

Well, that's my two cents.
