From: "matz (Yukihiro Matsumoto)" Date: 2012-04-10T18:51:13+09:00 Subject: [ruby-core:44262] [ruby-trunk - Feature #3963][Rejected] Map class in standard library Issue #3963 has been updated by matz (Yukihiro Matsumoto). Status changed from Assigned to Rejected I reject the original idea of Map inclusion to the core. Map and Hash are too similar. Matz. ---------------------------------------- Feature #3963: Map class in standard library https://bugs.ruby-lang.org/issues/3963#change-25799 Author: trans (Thomas Sawyer) Status: Rejected Priority: Normal Assignee: matz (Yukihiro Matsumoto) Category: Target version: 2.0.0 =begin Could we get a class like Ara Howard's Map (http://github.com/ahoward/map) included in Ruby's standard library? Map is a class that would get a lot of usage. We already see similar classes in other code like Rail's with it's HashWithIndifferentAccess, and my own spin-off from Ruby Facets, the Stash class. It's just one of those things that is genuinely useful. I am not partial to any particular implementation, but I trust Ara's skills and the short name "Map" is pretty nice too. (Just a side note: Personally I'd prefer the functionality of Map in place of Hash itself, since it has the functionality people want 80% or more of the time, but I realize that is likely to have too many backward compatibility issues for real consideration.) =end -- http://bugs.ruby-lang.org/
