#15233: You can always set fixity of (:), with no effect -------------------------------------+------------------------------------- Reporter: Iceland_jack | Owner: (none) Type: bug | Status: patch Priority: normal | Milestone: 8.8.1 Component: Compiler | Version: 8.5 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D5167 Wiki Page: | -------------------------------------+------------------------------------- Comment (by Ryan Scott <ryan.gl.scott@…>): In [changeset:"feb8a671a4e92922ddac108686f0eace97dd331f/ghc" feb8a67/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="feb8a671a4e92922ddac108686f0eace97dd331f" Improve generated `GHC.Prim` docs Summary: * Extended `genprimcode` to generate Haddock-compatible deprecations, as well as displaying information about which functions are LLVM-only and which functions can fail with an unchecked exception. * Ported existing deprecations to the new format, and also added a deprecation on `par#` (see Trac #15227). * Emit an error on fixity/deprecation of builtins, unless we are processing the module in which that name is defined (see Trac #15233). That means the following is no longer accepted (outside of `GHC.Types`): ``` infixr 7 : {-# DEPRECATED (:) "cons is deprecated" #-} ``` * Generate `data (->) a b` with docs and fixity in `GHC.Prim`. This means: GHC can now parse `data (->) a b` and `infixr 0 ->` (only in `GHC.Prim`) and `genprimcode` can digest `primtype (->) a b` (See Trac #4861) as well as some misc fixes along the way.
