Description updated

----------------------------------------
Feature #8987: map/collect extension which handles arguments
https://bugs.ruby-lang.org/issues/8987#change-47055

* 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).
