At the time ... to work round bugs in the libobjc code ... and to ensure 
that
any bugs in the mframe code were exposed as quickly as possible.

Also, because calling the libobjc code with illegal arguments causes a 
crash.

It would be nice to update the mframe code to -
1. handle simple types directly and cope with illegal types.
2. use libobjc to obtain info for more complex types.
