#12618: Add saturated constructor applications to Core -------------------------------------+------------------------------------- Reporter: simonpj | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): Oh, and fun fact: It might be possible to remove `App` completely and replace it with a pattern synonym here: Due to `compressArgs ty [x] = [x]`, `Apps f 1 [e]` is equivalent to `App f e`. So this might not actually be a serious change to core, nor might it be increasing the number of constructors: Using a bidirectional smart constructor (which does optimizes the representation under the hood) this can hopefully be a completely transparent optimization of the representation. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12618#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
