[GHC] #8469: GHCi reports out-of-scope type family instances with :info
#8469: GHCi reports out-of-scope type family instances with :info ------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.7 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- I have {{{ {-# LANGUAGE TypeFamilies #-} module A () where type family F a type instance F Int = Bool }}} {{{ module B where import A }}} In GHCi: {{{ Prelude> :load B [1 of 2] Compiling A ( A.hs, interpreted ) [2 of 2] Compiling B ( B.hs, interpreted ) Ok, modules loaded: B, A. *B> :i Int data Int = GHC.Types.I# GHC.Prim.Int# -- Defined in ‛GHC.Types’ <snip> type instance A.F Int -- Defined at A.hs:6:1 *B> }}} This last output from `:info` should be suppressed, I would think. (I agree it should be printed with `:info!`.) Note the `()` in module `A`'s export list. This is a regression from 7.6.3, where the out-of-scope type family instance is not printed. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8469 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
