The relevant code is (noting that ParserCombinators is from base): {{{ qual_name mod occ | [] <- unqual_gres , modulePackageKey mod `elem` [primPackageKey, basePackageKey, thPackageKey] , not (isDerivedOccName occ) = NameUnqual -- For names from ubiquitous packages that come with GHC, if -- there are no entities called unqualified 'occ', then -- print unqualified. Doing so does not cause ambiguity, -- and it reduces the amount of qualification in error -- messages. We can't do this for all packages, because we -- might get errors like "Can't unify T with T". But the -- ubiquitous packages don't contain any such gratuitous -- name clashes. -- -- A motivating example is 'Constraint'. It's often not in -- scope, but printing GHC.Prim.Constraint seems overkill. }}} from {{{ commit 547c597112954353cef7157cb0a389bc4f6303eb Author: Simon Peyton Jones <simonpj@microsoft.com> Tue Apr 7 05:48:30 2015 Committer: Simon Peyton Jones <simonpj@microsoft.com> Tue Apr 7 07:10:22 2015 Reduce module qualifiers in pretty-printing }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/10579#comment:1> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
