I rate this obvious seeming fact as one of the most important things
I've learnt about numerical linear algebra in my career. The number of
times I've seen (and...oops...written it myself) code that copies data
out of some structure into some standard matrix structure when the
original structure could itself have been seen as a function that
transforms vectors is scary. It pays to think functionally.
