Hmm.  That looks like it will require a deeper dive into the theory than I 
want to make right now.  I don't yet understand what a kind is yet, much less 
how to write an appropriate kind signature.  It appears to be a somewhat 
disconcerting fact that learning Haskell requires reading original research 
papers on type theory and lambda calculus.  I suppose I need to get over my 
reluctance and dive into some of that -- but I lack the big slabs of time 
needed to immerse myself in it enough to make useful progress.

Learning Haskell appears to be something one should do as a college 
student :-)
