my $match = new Net::ACL::Match::Regexp([^65001 [0-9 ]+ 65002$,2]);
This is the constructor for Net::ACL::Match::Regexp objects.
It returns a reference to the newly created object.
It takes one argument. If the argument is a array reference with one element,
the element will be used as a regular expression pattern to matched with the first
argument to the match method.
If an array reference has more then one element, the second element should be
the argument number to be matched in the match method.
Otherwise, the value it self will be used as a regular expression pattern to match the
first argument of the match method.
