class Hash
# Returns a new hash with +self+ and +other_hash+ merged recursively.
#
# h1 = { a: true, b: { c: [1, 2, 3] } }
# h2 = { a: false, b: { x: [3, 4, 5] } }
#
# h1.deep_merge(h2) # => { a: false, b: { c: [1, 2, 3], x: [3, 4, 5] } }
#
# Like with Hash#merge in the standard library, a block can be provided
# to merge values:
#
# h1 = { a: 100, b: 200, c: { c1: 100 } }
# h2 = { b: 250, c: { c1: 200 } }
# h1.deep_merge(h2) { |key, this_val, other_val| this_val + other_val }
# # => { a: 100, b: 450, c: { c1: 300 } }
def deep_merge(other_hash, &block)
dup.deep_merge!(other_hash, &block)
end
# Same as +deep_merge+, but modifies +self+.
