This way, you won't need to write: ``` .. qmp-example:: :annotated: Blah blah .. code-block:: QMP -> { "lorem": "ipsum" } ``` But instead, simply: ``` .. qmp-example:: :annotated: Blah blah:: -> { "lorem": "ipsum" } ``` Once the directive block is exited, whatever the previous default highlight language was will be restored; localizing the forced QMP lexing to exclusively this directive. Note, if the default language is *already* QMP, this directive will not generate and restore redundant highlight configuration nodes. We may well decide that the default language ought to be QMP for any QAPI reference pages, but this way the directive behaves consistently no matter where it is used.
