      Oh, I see. There is an "or similar" in your code ;-) FWIW what you have looks similar to @larsr_h's original TypeClass type class.

      Oh, but the "or similar" (!) is only in my code, not users' code (in the form of Lazy)… I'll revisit @larsr_h's Typeclass² for inspiration!

          I think Google Scholar will probably get you to a non-paywalled version.
