I might not be so much about the language but about the paradigm. Certainly going from Java to C++ might not be that different but through in something like Haskell and you almost have to entirely rethink your solution.
Furthermore, programming languages are written in English. A real language cannot be written in another language.
I'm not a linguist nor a programmer, but I'm trilingual, and I have scripted at a basic level. And honestly, although I see the resemblance, I don't think that programming languages and real languages work the same way.
