tokeniser ignores the UTF-8-ness of C<PL_rsfp>, or any SVs returned from

+=head2 The yada yada yada operators
+
+Perl 6's Synopsis 3 says:
+
+I<The ... operator is the "yada, yada, yada" list operator, which is used as
+the body in function prototypes. It complains bitterly (by calling fail)
+if it is ever executed. Variant ??? calls warn, and !!! calls die.>
+
+Those would be nice to add to Perl 5. That could be done without new ops.
