    For one project I'm opting to use pipelines of sorts. I'll
    generate intermediate files, and transform them further.

    Using this method, I can see how one would create a two step
    process, or three step process, but not how one would create a
    properly recursive process.

    Where I'm using Saxon 8.X, I'll start using FXSL.

    I can see how callbacks, and curried functions could be used to
    define an API, but I'm sure there is a lot to learn in practice. 

    Where can I see examples of an API specified in FXSL? Or is it
    so young that I sould study Haskell for best practice?

    Also, I see no lists for FXSL. Is this the correct forum in
    which to field new user questions?

    Thanks for recommending this. I'm looking forward to finally
    learning functional programming.
