I'll test this out.

I can't see why --- certainly not treat it as an unambiguous insertion,
fait accompli.  You can't even see what it's going to complete next.

Um.  I'm still a bit vague as to how all this works.  Can we prevent
this behaviour happening with argument-rest?  After all, it's being
smuggled in behind our back anyway --- it's not specified either in the
styles, nor in the list of tags I'm explicitly generating.

Can we make the system remember we're in a nested loop?  And then inside
it can be more lenient?  Or some combination of the tow?  Or something?

I don't think I'm going to be much help here.
