[Haskell-cafe] The (!) operation

[Christopher Done]

‘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!
