GroovY vs RubY {Closures} - II

Surprisingly while tryin to implement a simple closure example in ruby i overlooked a kouple of immensely helpful methods. with the excitement kooled down now, i present a simpler variant of the same.

class Array

def apply
collect! { |number| yield number }
end

end
a=[1,2,3]
a.apply { |i| i * i }
p a.to_s
