Subject: [ruby-core:62954] [ruby-trunk - Feature #8987] map/collect extension which handles arguments

Issue #8987 has been updated by Nobuyoshi Nakada.

Related to Feature #4146: Improvement of Symbol and Proc added

----------------------------------------
Feature #8987: map/collect extension which handles arguments

* Target version: current: 2.2.0
----------------------------------------
Please consider extending map/collect by allowing additional arguments to be passed to proc, like:
A: [1,2,3,4].map :+, 4
and/or
B: [1,2,3,4].map 4, &:+

=> [5, 6, 7, 8]

Variant A is probably more readable. Variant B is more versatile (allows arbitrary arguments to be passed to block).
