I suppose I should have been clearer in my statement about ``unless they need to talk about the language itself''. Of course, all people that work in a group of programmers need to talk about the language itself all the time. But if one was working alone, there would be no need for there to even be a term to describe it, as long as you know what it does. Sorry for the lack of clarity.

Edit: I've always been fascinated by the British schooling system of O-levels, A-levels, etc. This is probably based on the fact that I don't really know what they are. Please break my fascination and explain this to me.
