ANYSXP is a valid internal type on the C level, and
src/main/util.c will make typeof(ob) return "any"
if you can get your hands at an R level object of that type.
I'd guess you can only get it currently by using .Call() and
using your own C code, .. but at least that way it must be possible.

I did not investigate in details, but yes, I vaguely remember we
had fixed that. So indeed, it's fine you omitted the para in
your patch.

Thank you, Scott.
Indeed, I've finally carefully looked at the patch, and applied
it - for R-devel, to become R 3.1.0 in April.
