RAA - hashslice

HashSlice is a Ruby module that adds slicing to the builtin Hash class. Slicing is the ability to fetch and assign to more than one key-value pair of the hash.

require 'hashslice'

hash = {'a' => 1, 'b' => 2, 'c' => 3}

# Slice reference
hash['a', 'b'] # -> [1, 2]
hash['a'] # -> 1

# Slice assignment
hash['a', 'b'] = 7, 8

hash # -> {'a' => 7, 'b' => 8, 'c' => 3}
