 PIR supports a convenient syntax for returning any number of values from a sub
 or closure:
 
-
-To test whether a value was returned, declare it C<:optional>, and follow it
-with an integer register declared C<:opt_val>:
-
-=begin PIR_FRAGMENT_INVALID
-
-    ($P10 :optional, $I10 :opt_val) = do_something($P1, $S3)
-
-=end PIR_FRAGMENT_INVALID
-
-Both of these affect only the signature provided via C<get_results>.
-
-[should also describe :flat, :slurpy, :named, ..., or at least provide a
-reference.  -- rgr, 25-May-08.]

-=begin PIR_FRAGMENT

-    # Call the sub in $P8, with continuation (created earlier) in $P9.
