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.
