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
+and tabulate the differences in Perl 6. The annotated view of changes 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:
=over 4
-=item * C<cc (cc.U)>
+=item * C<cc> (in F<cc.U>)
This variable holds the name of a command to execute a C compiler which
can resolve multiple global references that happen to have the same
name. Usual values are F<cc> and F<gcc>.
Fervent ANSI compilers may be called F<c89>. AIX has F<xlc>.
-=item * ld (dlsrc.U)
+=item * C<ld> (in F<dlsrc.U>)
This variable indicates the program to be used to link
libraries for dynamic loading. On some systems, it is F<ld>.
