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

----------------------------------------
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).
