So, in order to leave the door open for implicit CALL (which nobody's
ever proposed or tried to implement AFAIR), you're willing to see every
other proposal for new plpgsql statements go down the drain due to
objections to new reserved words? I think your priorities are skewed.
(If we did want to allow implicit CALL, I suspect that things could be
hacked so that it worked for any function name that wasn't already an
unreserved keyword, anyway. So you'd be no worse off.)

I can't say that either of those excite me particularly, so the idea
that those two are the only new statements we'd ever want to add seems
improbable.
