Agreed on the fewer examples, I’ll trim this down. :)

As for bringing the examples to `mocking_dsl_spec.rb` and leaving `mocking_dsl_kwargs.rb` with only `ExampleFooKwargs`: should then the specs brought into `mocking_dsl_spec.rb` be conditionally loaded depending on whether `ExampleFooKwargs` is defined (or Ruby ≥ 2.0)?
