Well as far as efficiency, these are typically micro-considerations --
you're talking in terms of cycles. Cross those bridges when you come
As with overcomplication, the story is the same as with all
abstraction: it's a fine balance between how much work they are to
declare, their cognitive benefit, and how many times they are used.
Haskell has wonderfully lightweight declarations, so that trade-off
favors the new abstraction much more quickly than in other languages.
