Clean up `Coercible` plumbing
Currently, the way Coercible
is exported (with an data type in GHC.Types
and a built-in !TyCon exported in GHC.Prim
) works, but is confusing and should be cleaned up. Probably by exporting it directly from GHC.Types
.
Care needs to be taken that ghci and haddock display the data from modified built-in !TyCon; when I tried that a while ago it was displayed as a regular data type by one of them. If that is still the case and I didn't just do a mistake back then, this probably needs to be understood and fixed.
