Description

There are a number of patterns that occur multiple times in Lean, such as having a type class that represents the transitive closure of some other class (MonadLift vs MonadLiftT, MonadEval vs MonadEvalT, the various chainings of Coe*).

It would be useful to name these patterns and document their design considerations explicitly, rather than having multiple similar descriptions.
