#10963: Beginner-targeted language extension -------------------------------------+------------------------------------- Reporter: kanetw | Owner: Type: feature request | Status: patch Priority: normal | Milestone: 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: | Differential Rev(s): Phab:D2136 Wiki Page: | [wiki:Design/GHCi/Type] | -------------------------------------+------------------------------------- Comment (by aavogt): `:set +t` seems to have been forgotten. I think the defaulted type could be tacked on if you are shown a value, since that value was calculated with a particular instance. For example: {{{
:set +t 1+1 2 -- current output it :: Num a => a }}}
{{{
:set +t 1+1 2 :: Integer -- proposed it :: Num a => a }}}
This case shouldn't change because nothing was evaluated {{{
:set +t let (x:xs) = [1 .. ] x :: (Num t, Enum t) => t xs :: (Num t, Enum t) => [t] }}}
