class Hash
unless method_defined?(:slice)
# Adds `Hash#slice` for Ruby 2.4.
# Returns a hash containing a subset of keys. If a given key is not
# in the hash, it will not be returned.
#
# @return [Hash] hash containing only the keys given.
#
# @example
# { one: 1, two: 2 }.slice(:two, :three) #=> { two: 2 }
