Regex pattern objects are magical. Overloading doesn't even come into play.

Magical is right. This took me by surprise.

use overload; use Scalar::Util qw( blessed ); use Test::More 'tests' => 4; my $rx = qr/a/; ok blessed $rx, 'Regexp is blessed'; ok ! overload::Overloaded( $rx ), 'Regexp is overloaded'; ok ! overload::Method( $rx, q{""} ), 'Regexp has q{""} overloaded'; isnt "$rx", overload::StrVal( $rx ), 'StrVal of regexp isnt regexp stringified';

    ok ! overload::Overloaded( $rx ), 'Regexp is overloaded'; ok ! overload::Method( $rx, q{""} ), 'Regexp has q{""} overloaded';
    I'm confused shouldn't it say "is not" and "has not"?

      You're right. I originally wrote the descriptions to match the tests, and then I was surprised when I ran them (they failed). After that, I reversed the tests and forgot to rephrase the descriptions.
