To follow-up to my own message, I really don't think any new language
features, really, are required.  You simply make the extension of
allowing a data pointer to be cast to a function pointer.  The contents
of the area pointed to by the data pointer are implementation-dependent.
If the pointed-to data cannot be converted into a function of the
required type, (function *)NULL results.

Everything else can get hidden underneath the table, behind the curtains...
