GHC.Tc.Deriv.Generate
Description
Generating derived instance declarations
This module is nominally `subordinate' to GHC.Tc.Deriv, which is the
`official' interface to deriving-related things.
This is where we do all the grimy bindings' generation.

Produces a function binding. When no equations are given, it generates a binding of the given arity and an empty case expression for the last argument that it passes to the given function to produce the right-hand side.
