There are countless parsing libraries, compilers and cutting edge research done in Haskell. My guess is that you are thinking of NumPy and similar wrappers over older C/Fortran code. A computer scientist would seek to design something better, perhaps by exploiting algebraic properties not considered by NumPy. Universities teaching Python is a relatively recent phenomenon, perhaps to appease industry. EDIT: cabal came from industry and was based on ideas from the Java, Python, Ruby communities. The Nix packager better embodies the ideas of Haskell.
