use WWW::Mechanize::Cached;
use Some::Module qw(some_method);

my $url = '...';
my $result = some_method( $url );

some_method()使用自己的get()形式LWP :: Simple.
我怎么能用这个脚本中的my_get()覆盖get()？

sub my_get {
    my $url;
    my $mech = WWW::Mechanize::Cached->new();
    $mech->get( $url );
    my $content = $mech->content( format => 'text' );
    return $content;
}
