Feature #8987

Updated by nobu (Nobuyoshi Nakada) over 7 years ago

Please consider extending map/collect by allowing additional arguments to be passed to proc, like: 
 A: `[1,2,3,4].map [1,2,3,4].map :+, 4` 4 
 and/or 
 B: `[1,2,3,4].map [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).
