    Throw an error when enum has a weird argument list

        This protects users against this kind of construct:

            has type => (
                is       => 'rw',
                isa      => enum ['foo', 'bar', 'baz'],
                required => 1,
            );

        This code will NOT do what you want, being parsed like:

            enum(['foo', 'bar', 'baz'], 'required', 1);

        which ends up with an enum named by a stringified array reference
        where the valid values are "required" and "1". And the required-ness
        of the attribute is obviously not intact. So this attribute is
        really FUBAR.
