 144  * param_count          - Number of arguments to the method
 145  * expected_btypes      - Allowed type(s) for the return value.
 146  *                        0 means that no return value is expected.
 147  *
 148  * For methods that return packages, the next entry in the table contains
 149  * information about the expected structure of the package. This information
 150  * is saved here (rather than in a separate table) in order to minimize the
