=head1 NAME
Path::Dispatcher::Rule::Regex - predicate is a regular expression
=head1 VERSION
version 1.08
=head1 SYNOPSIS
my $rule = Path::Dispatcher::Rule::Regex->new(
regex => qr{^/comment(s?)/(\d+)$},
block => sub { display_comment(shift->pos(2)) },
);
=head1 DESCRIPTION
Rules of this class use a regular expression to match against the path.
=head1 ATTRIBUTES
=head2 regex
The regular expression to match against the path. It works just as you'd expect!
The capture variables (C<$1>, C<$2>, etc) will be available in the match
object as C<< ->pos(1) >> etc. C<$`>, C<$&>, and C<$'> are not restored.
