Contextclj/sprotocol
Abstraction that establish a membership of types with one concrete monad.
This is a way that cats establishes the relation between a type and the monad that that should play.
A great example es Maybe monad type Just. It implements this abstraction for establish that Just is part of Maybe monad.
