instance method Enumerable#each_entry

each_entry -> Enumerator

each_entry {|obj| block} -> self

Calls <i>block</i> once for each element in <i>self</i>, passing that element as a parameter, converting multiple values from yield to an array.

class Foo
  include Enumerable
  def each
    yield 1
    yield 1,2
  end
end
Foo.new.each_entry{|o| print o, " -- "}

produces:

1 -- [1, 2] --
