in a way, `Data.Set.Base.Set` is the “original”, proper name for Set, everything else is just a local view on the name. So, are you maybe looking for a way to get the “most natural way” to print a name in a certain module context? This functionality must exist somewhere, as ghci is printing out errors this way. But it certainly would require an additional argument to tyconString, to specify in which module to print the name.
