Read perldoc perlvar:
$<digits>
Contains the subpattern from the corresponding set
of parentheses in the last pattern matched, not
counting patterns matched in nested blocks that have
been exited already. (Mnemonic: like \digits.)
These variables are all read-only.
Example:
if ($line =~ /^(\w+)\s*=\s*(.*)/) {
print "setting '$1' to '$2'\n";
$config{$1} = $2;
}
