What is a Ruby equivalent for Python's “zip” builtin?

zip(a, b).all? {|pair| pair[0] === pair[1]}

[1,2].zip([3,4]) => [[1,3],[2,4]]

a.zip(b).all? {|pair| pair[0] === pair[1]}

a.zip(b).all? {|a,b| a === b }

a.eql?(b)

a = %w[a b c]
b = %w[1 2 3]
c = ['a', 'b', 'c']

a.eql?(b) # => false
a.eql?(c) # => true
a.eql?(c.reverse) # => false

it "returns true if other has the same length and each pair of corresponding elements are eql" do
    a = [1, 2, 3, 4]
    b = [1, 2, 3, 4]
    a.should eql(b)
    [].should eql([])
end
