      Improve pattern synonym error messages (add `PatSynOrigin`) · 116528c8
      Rik Steenkamp authored
      Adds a new data constructor `PatSynOrigin Bool Name` to the `CtOrigin`
      data type. This allows for better error messages when the origin of a
      wanted constraint is a pattern synonym declaration.
      
      Fixes T10873.

      Improve accuracy of suggestion to use TypeApplications · e38c07bf
      Matthew Pickering authored
      The suggestion only makes sense when we try
      to use an as pattern in an expression context.
      
      It is misleading in the case of a lazy pattern and
      view pattern.

      Handle multiline named haddock comments properly · 6350eb11
      thomie authored
      Fixes #10398 in a different way, thereby also fixing #11579.
      
      I inverted the logic of the Bool argument to "worker", to hopefully make
      it more self-explanatory.

      (Alternative way to) address #8710 · 67393977
      Georgios Karachalias authored
      Issue a separate warning per redundant (or inaccessible) clause.
      This way each warning can have more precice location information
      (the location of the clause under consideration and not the whole
      match).
      
      I thought that this could be too much but actually the number of
      such warnings is bound by the number of cases matched against (in
      contrast to the non-exhaustive warnings which may be exponentially
      more).

      - Replace "PatSyn" with "PatternSynonym" in WarningFlag data
        constructors.
      - Deprecate "missing-local-sigs" in favor of "missing-local-signatures".

        "missing-exported-signatures".

      Add more type class instances for GHC.Generics · 673efccb

      GHC.Generics provides several representation data types that have
      obvious instances of various type classes in base, along with various
      other types of meta-data (such as associativity and fixity).
      Specifically, instances have been added for the following type classes
      (where possible):
      
          - Applicative
          - Data
          - Functor
          - Monad

      Overload the static form to reduce verbosity. · c1efdcc4
      Facundo Domínguez authored
      Static pointers are rarely used naked: most often they are defined at
      the base of a Closure, as defined in e.g. the distributed-closure and
      distributed-static packages. So a typical usage pattern is:
      
          distributeMap (closure (static (\x -> x * 2)))
      
      which is more verbose than it needs to be. Ideally we'd just have to
      write
      
          distributeMap (static (\x -> x * 2))
      
      and let the static pointer be lifted to a Closure implicitly. i.e.
      what we want is to overload static literals, just like we already
      overload list literals and string literals.
      
      This is achieved by introducing the IsStatic type class and changing
      the typing rule for static forms slightly:
      
          static (e :: t) :: IsStatic p => p t

      Address #11471 by putting RuntimeRep in kinds. · d8c64e86
      eir@cis.upenn.edu authored
      See Note [TYPE] in TysPrim. There are still some outstanding
      pieces in #11471 though, so this doesn't actually nail the bug.
      
      This commit also contains a few performance improvements:
      
      * Short-cut equality checking of nullary type syns
      
      * Compare types before kinds in eqType
      
      * INLINE coreViewOneStarKind
      
      * Store tycon binders separately from kinds.
      
      This resulted in a ~10% performance improvement in compiling
      the Cabal package. No change in functionality other than
      performance. (This affects the interface file format, though.)
      
      This commit updates the haddock submodule.
