#15721: Command `:show bindings` throws exception for bindings without `let` -------------------------------------+------------------------------------- Reporter: sighingnow | Owner: (none) Type: bug | Status: new Priority: high | Milestone: Component: GHCi | Version: 8.6.1 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: GHCi crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by mpickering): * keywords: => newcomer Comment: I can't reproduce this on linux so it seems like a windows problem. Two other strange things about `x = a` {{{ let x = 'a' x = 'a' }}} doesn't warn about name shadowing. If you inspect the heap representation of the two versions of `x` they are also different. The latter is a thunk whilst the former is just the character. Making `x = a` behave exactly like `let x = a` will probably fix this ticket the above two problems as well. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15721#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
