You can still do the same thing using lexicals (if you are allergic to using symbol-table variables). The only thing to be careful is to reuse the same push statement and same target array every time. This is adapted from the code in Re^3: Regexes: finding ALL matches (including overlap): 
{
  my @matches;
  my $push = qr/(?{ push @matches, $1 })/;

  sub match_all_ways {
      my ($string, $regex) = @_;
      @matches = ();
      $string =~ m/($regex)$push(?!)/;
      return @matches;
  }
}

print match_all_ways( "TXXXABCDGXXXCCCDTGYYYCCCYYYCC", qr/XXX.*YYY/ );

Technically, $push is not needed -- you could just include (?{push @matches, $1}) in the m// statement inline. However, I like this way as it makes it a much more obvious that this part of the regex is only compiled once.
