[GHC] #11585: Overload the static form to reduce verbosity
#11585: Overload the static form to reduce verbosity -------------------------------------+------------------------------------- Reporter: | Owner: facundo.dominguez | facundo.dominguez Type: feature | Status: new request | Priority: normal | Milestone: 8.0.1 Component: Compiler | Version: 7.10.3 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- 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 }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11585 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
