#9394: Show data/type family instances with ghci's :info command -------------------------------------+------------------------------------- Reporter: s9gf4ult | Owner: Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.6.3 Component: GHCi | Keywords: ghci Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by simonpj): Dear s9gf4ult (I wonder who you are in real life?) That makes sense. For classes, actually `:info Eq` lists all the instances of `Eq`, so maybe that should happen for `type` and `data` families too? Then adding arguments could filter the list to just the instances that match the pattern given? Would you, or anyone else, like to specify the feature and offer a patch?
