You didn't, @o_guest, I was replying to @KreuzUQuer's comment to prototype in matlab and *then* using a "serious" language.
Sure, use whatever works best for rapid prototyping or quickly testing some model/method :-)
My point was just it's nice to work in a language where the prototype can be used as the basis of the "real" code 
that's so legit. Yep.
