Hi,

While the impact seems low, some relatively trivial MonadFail instances seem to be missing still, including: Option, First, Last, Proxy, WrappedMonad. Also the non-base containers:Seq. These were not specifically discussed either [1].

Thoughts? Any other things that are still overlooked?

A PR to add the instance for sequences would be accepted promptly.
