So it would be useful for someone to compare the Perl 6 smartmatch table
as of February 2006 L<http://svn.perl.org/viewvc/perl6/doc/trunk/design/syn/S03.pod?view=markup&pathrev=7615>
and the current table L<http://svn.perl.org/viewvc/perl6/doc/trunk/design/syn/S03.pod?revision=14556&view=markup>
-and tabulate the differences in Perl 6. The diff is

With that done and published, someone (else) can then map any changed Perl 6
semantics back to Perl 5, based on how the existing semantics map to Perl 5:
