Comment:

 My instinct is that this feature is beyond the scope of GHCi and is better
 incorporated into another tool (perhaps
 [https://github.com/HeinrichApfelmus/hyper-haskell HyperHaskell]?), but
 others may differ in opinion. Regardless of my opinion on the feature, the
 way to incorporate this user-facing change is to write a
 [https://github.com/ghc-proposals/ghc-proposals ghc-proposal].

 I'll also note that this will be hard to implement, as GHC does not store
 the user-written definition of functions anywhere.

 Given that this belongs as a ghc-proposal instead of a Trac ticket, I will
 close. This ticket can be reopened when the proposal is accepted.
