    }

}

<?hh //strict

<<Tag('important')>>
class TaggedTarget
{
}

<?hh //strict

namespace example;

$attribute = Tag::findByClassName(TaggedTarget::class);
var_dump($attribute->value()); // Tag attribute instance

$attribute = Tag::findByClass(new ReflectionClass(TaggedTarget::class));
var_dump($attribute->value()); // Tag attribute instance

MethodAttribute
