I suppose, why take away those use cases only to later weld them back together with Python, maybe having to do it with a bunch stringly typed ffi calls. Now you have three or four languages/programs/DSLs to deal with, each with impedance mismatches and they can only interact through the central Python program. Or you can collapse your stack down one technology that integrates it all in such a natural way that you can list recursive parsing and linear constraint optimization in the same breath and still say it's not a general purpose language.
