#10972: Add a :binfo (beginner info) GHCi command -------------------------------------+------------------------------------- Reporter: kanetw | Owner: kanetw Type: feature request | Status: new Priority: normal | Milestone: 8.0.1 Component: Compiler | Version: 7.10.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #10963 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Here's an idea: use the `default` list. We could even add `(->)` to that list. It would be otherwise pointless, but by putting it in the list, we get the specialization behavior above. And it's user-customizable. So if, say, an instructor is using a custom list type or introducing the `Foldable Maybe` instance, that person could then just change the `default` list and get the new specializations. The `default` list also tends to be somewhat short, yielding about the right number of specializations in the output. We could also consider just adding this behavior to `:info`. Perhaps a quick user poll is in order? Nitpick: I would prefer we "specialise" instead of "specialize". Since we're writing the '''Glasgow''' Haskell Compiler, it seems we should use the variant of English spoken (wait -- English spoken in Glasgow is nigh incomprehensible, to me at least)... er... ''written'' in Glasgow. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10972#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
