All the initial work on this was done fy 'archblob' (fcsernik@gmail.com); thank you! I reviewed the patch, started some tidying, up and then ended up in a huge swamp of changes, not all of which I can remember now. But: * To suppress kind arguments when we have -fno-print-explicit-kinds, - IfaceTyConApp argument types are in a tagged list IfaceTcArgs * To allow overloaded types to be printed with =>, add IfaceDFunTy to IfaceType. * When printing data/type family instances for the user, I've made them print out an informative RHS, which is a new feature. Thus ghci> info T data family T a data instance T Int = T1 Int Int data instance T Bool = T2 * In implementation terms, pprIfaceDecl has just one "context" argument, of type IfaceSyn.ShowSub, which says - How to print the binders of the decl see note [Printing IfaceDecl binders] in IfaceSyn - Which sub-comoponents (eg constructors) to print * Moved FastStringEnv from RnEnv to OccName It all took a ridiculously long time to do. But it's done!
