That’s one way yeah. Or you’d could to make the grammar context sensitive / apply a "lexer hack”. Probably other ways to deal w/ context sensitivity as well. Joe’s proposed syntax seems pretty explicit, and hopefully it’sdsimple to plumb / capture that info in the lexer. (I’m ignorant of the implementation of Swift’s front-end unfortunately!) -Colin
