Repeated thanks to you, Adam! Your code is brilliantly simple.
Sadly, I cannot reproduce the behaviors in your comments on my ghci
(7.6.1) .
Can we guess why? The version of packages we are using?
Mines are here.

Dear Haskellers,
I'd like to announce a small library "tie-knot":
"Ties the knot" on a given set of structures that reference each other by
keys - replaces the keys with their respective values. Takes Map k (v k)
and converts into Map k v' where v' is the fixed point of v.
Motivation: I ne
I guess you have a point here:
1. The definition of the MonadWriter operations does not need the Monoid
operations.
Hence, the class constraint Monoid w should be removed.
2. The formulation of the MonadWriter laws (which are sadly missing from
the documentation) would need the Monoid oper
