Module `Accessor.Of_monad`

Of_monad is similar to Of_applicative. There are two differences.

Many functions generated by Of_monad can distinguish between `Sequential traversals and `Parallel traversals. This matters when you want to use monadic sequencing to control side effects. The functions generated by Of_applicative are only able to use the `Parallel behavior. Here are a couple examples of when you might care about this:

When using Or_error, map ~how:`Sequential t at ~f would terminate the traversal as soon as an error has occurs. map ~how:`Parallel t at ~f would apply f to everything before attempting to compose the results, and if there is more than one error they will be combined.
When using Deferred, map ~how:`Sequential t at ~f would wait for each deferred to become determined before moving on to the next value. map ~how:`Parallel at ~f would apply f to everything and then wait for the results to become determined asynchronously.

Parameters

M : sig ... end
