Subject: [ruby-core:57679] [ruby-trunk - Feature #8987][Open] map/collect	extension which handles arguments


Issue #8987 has been reported by sowieso (So Wieso).

----------------------------------------
Feature #8987: map/collect extension which handles arguments
https://bugs.ruby-lang.org/issues/8987

Author: sowieso (So Wieso)
Status: Open
Priority: Normal

Category: core
Target version: current: 2.1.0


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).
