Allow to delete functions. One can already undef them, but they're still
in the stash.
+=head2 C</w> regex modifier
+
+That flag would enable to match whole words, and also to interpolate
+arrays as alternations. With it, C</P/w> would be roughly equivalent to:
+
+ do { local $"='|'; /\b(?:P)\b/ }
+
+See L<http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2007-01/msg00400.html>

=head2 optional optimizer
Make the peephole optimizer optional. Currently it performs two tasks as
tokeniser ignores the UTF-8-ness of C<PL_rsfp>, or any SVs returned from
source filters. All this could be fixed.
+=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.
