Removing all of the objects of a particular class

To quickly remove all of the objects of a particular class, call the remove_all method on the class name in question:

MT::Foo->remove_all();

On success, remove_all will return some true value; on failure, it will return undef, and you can retrieve the error message by calling the errstr method on the class name:

MT::Foo->remove_all
    or die "Removing all foo objects failed: ", MT::Foo->errstr;
