IMHO .WAIT is similar to an instruction reorder barrier in code - nothing
caused by the right hand side should be moved across to the left. Anything
else will only cause confusion.
So I'd say: yes, make it recursive, and no, don't bother to provide
Hmm, .ORDER sounds like a different notation for the same semantics, which
would imply to treat it just the same. (Though the different notation does
not associate the "barrier" idea.)
