‘Ello.
Is there a generalization of this operator? It's all over the place,
it's basically
(!) :: (Monad m, Indexed collection index value) => index ->
container -> m value
We have `(!!)` on lists, `(!)` on maps, vectors, json objects, …
(doesn't seem there's one for bytestring)
(Though I seem to recall the monadic return value being frowned upon
but I don't recall why.)
Thoughts?
Ciao!
