This is the primary motivation of the TTC (Textual Type Classes) library: https://hackage.haskell.org/package/ttc.
It provides a Render type class that is analogous to Show and a Parse type class that is analogous to Read. No instances are declared so that users of the library can implement instances as required for each application, but default instances for core types are available.
Not related to the main point of the thread, but we really need a way to signal certain libraries as the "go to solution" for a problem without including them in "base". A note on the Show/Read class documentation saying that the best solution for "showing" human text is certain library would be great. -- -- Rubén -- pgp: 4EE9 28F7 932E F4AD
