Yes, that one annoys me fairly often (typically with an arg named `function`).

In theory, yes.  That could cover `condition-case` as well ;-)

I think it'd be nice to use this spec for other things than just
debugging [ I remember a discussion a few .. months? .. back where
another possible use came up... oh yes, it was in the discussion about
preserving source-code location, where we could make use of this info
in order to know when the sexp is "code" which can then come with extra
annotations vs "data" in which case we need the unannotated sexp.  ]
