#10365: Implement Semigroup as a superclass of Monoid Proposal (Phase 1) -------------------------------------+------------------------------------- Reporter: gidyn | Owner: quchen Type: feature request | Status: patch Priority: high | Milestone: 8.0.1 Component: libraries/base | Version: 7.10.1 Resolution: | Keywords: report-impact Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D1284 Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): Right. `Data.NonEmpty` looks interesting, but a tad too interesting for a plain non-empty-list-type suitable for base. With all the others, the data type definition is equivalent, and rest of the API seems to be straight forward to me. So I have no qualms about this particular color of the shed. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10365#comment:38 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
