In the programming-centric IBs I know of I have seen zero representation whatsoever of linguists. It's strange, considering the predominance of PLT. Now that I think of it, I haven't seen much talk about formal language theory either.
Is it that both fields have very little overlap?
Most of the discussion I've seen on programming languages revolves around the structure of languages and how they affect their use by people. I would like to see a sort of comparative approach between families of natural languages and those of programming languages.
