Isn’t `multirec` a function for making hylomorphisms? The recursive dividing is the anamorphism, and the combining of the results is the catamorphism.

As written, however, `multirec` does not efficiently compose. For two constructions to be compatible, they’d have to share their decomposition strategy, including `indivisible` and `divide`. `value` probably composes neatly, but `combine` is a little thorny as the current implementation does two jobs: Processing the data and reconstructing the form of the data.

A composable `multirec` does sound interesting, however. Hmmm...
