#14170: 8.2.1 regression: GHC fails to simplify `natVal` -------------------------------------+------------------------------------- Reporter: vagarenko | Owner: Bodigrim Type: bug | Status: new Priority: high | Milestone: 8.2.3 Component: Compiler | Version: 8.2.1 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 simonpj):
I'm in great favour of adding Natural literal into core. It was untrivial and I didn't pursue that back then,
As comment:2 says, it's not trivial in the sense of "only 3 lines of code", but it is trivial (or at least easy) in the sense of "just follow the pattern of `Integer`". I often find myself liking things that are simple and explicable even if they do a bit more duplication than we'd ideally like. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14170#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
