    # Improves it_should_behave_like in some ways:
    # - It scopes the reused examples so #let und #subject does not bleed into the reusing example groups
    # - It allows to parametrize the reused example group by appending a hash argument.
    #   Every key/value pair in the hash will become a #let variable for the reused example group
    # - You can call it with a block. It will be available to the reused example group as let(:block)
