OK, here is the answer: http://www.perldoc.com/perl5.6.1/pod/perlre.html says: The numbered variables ($1, $2, $3, etc.) and the related punctuation set ($+, $&, $`, and $') are all dynamically scoped until the end of the enclosing block or until the next successful match, whichever comes first.
and 5.8.4 is the same except adding $^N (whatever that is). So it is not possible in Perl 5. Note that these numbered variables are somewhat like global variables, and go do "action at a distance". Is there going to be a way in perl 6 to control this better?
