The strategy I used when implementing Apple high-level events on the
MacHugs was to pass over strings only: I found two different foreign
interfaces in the C source code, combined them in order to provide
conversions back and forth to lazy Haskell/strict C strings. Then I
hardwired some new primitives in a new module that must be loaded in order
to call my extensions in C.
