+% For raw, must switch into @tex before parsing the argument, to avoid
+% setting catcodes prematurely. Doing it this way means that, for
+% example, @inlineraw{html, foo{bar} gets a parse error instead of being
+% ignored. But this isn't important because if people want a literal
+% *right* brace they would have to use a command anyway, so they may as
+% well use a command to get a left brace too. We could re-use the
+% delimiter character idea from \verb, but it seems like overkill.
