A good idea... maybe... (Score 1)

Ive always felt that using multiple languages for applications is a very good idea. The ability to use perl for something like parsing data for a c program comes to mind as a very obvious example. You get the performance of C with the ease and power of programming (the parsing part atleast) in perl. However i think there are probably some serious preformance drawbacks to using this method, though im really not sure. Anyone care to enlighten?
