I don't remember all the details, but I had a look at this in the
standard about a year ago and the behavior it mandated wasn't trivially
implemented using our existing mechanism.  I mentioned the issue of a
stack of user authorizations that is set up whenever a "routine"
(function) is entered, during last year's PGCon developer's meeting.  I
intended to have a look at implementing that, but I haven't done
anything yet.  What was clear to me was that once I explained the
problem, everyone seemed to agree that fixing it required more than some
trivial syntax rework.
