Calls the block with successive elements as long as the block returns a truthy value; returns an array of all elements after that point:
Example
(1..4).drop_while{|i| i < 3 } # => [3, 4] h = {foo: 0, bar: 1, baz: 2} a = h.drop_while{|element| key, value = *element; value < 2 } a # => [[:baz, 2]]
With no block given, returns an Enumerator.
