expect a message on any instance of a class

Use any_instance.should_receive to set an expectation that one (and only
one) instance of a class receives a message before the example is completed.

Scenarios
expect a message on any instance of a class
Given
a file named "example_spec.rb" with:
describe "any_instance.should_receive" do
  it "verifies that one instance of the class receives the message" do
    Object.any_instance.should_receive(:foo).and_return(:return_value)

    o = Object.new
    o.foo.should eq(:return_value)
  end
end
When
I run rspec example_spec.rb
Then
the examples should all pass
