Issue #11653 has been updated by Yukihiro Matsumoto. Assignee changed from Yukihiro Matsumoto to Nobuyoshi Nakada Accepted. Matz. ---------------------------------------- Feature #11653: Add to_proc on Hash https://bugs.ruby-lang.org/issues/11653#change-54774 * Author: Daniel P. Clark * Status: Open * Priority: Normal * Assignee: Nobuyoshi Nakada ---------------------------------------- Procs can be called the same way a hash is with `[]`. But a Hash is not mappable as a Proc. ~~~ruby my_hash = ->key{{ a: 1, b: 2, c: 3, d: 4, e: 5, f: 6 }[key]} my_hash[:a] # => 1 [:e, :a, :b, :f, :c, :d].map(&my_hash) # hash is now mappable # => [5, 1, 2, 6, 3, 4] ~~~ This seems so straight forward I believe it should be part of the language itself with the `.to_proc` method call. -- https://bugs.ruby-lang.org/ |
