Summary: Allow stubs to yield consecutive values

Initial Comment:
Scott Taylor asked,

I have a mock of an instance of a class which descends from Array:

class ArrayDescendent < Array; end

#... in the specs...
@descendent = mock ArrayDescendent

How would I stub out ArrayDescendent#each, which is inherited from
Array, to return multiple values successively?  I could use
and_yield, but that is raising an arity error (the anonymous function/
block should expect only *one value at a time, but and_yield is
yielding both values once).  Should I be using a lambda expression here?




This patch provides the #and_yield_consecutively method for mocks and stubs.
