Array#zip_with

Array#zip_with method inspired by Haskell's zipWith function.

Add this line to your application's Gemfile:

gem 'array_zip_with'

$ bundle

Or install it yourself as:

$ gem install array_zip_with

a = [1, 2, 3]
a.zip_with([3, 2, 1]) { |x, y| x + y } # => [4, 4, 4]

a = [1, 2, 3]
a.zip_with([3, 2, 1], :+) # => [4, 4, 4]
