Re: generalized lvalues -- patch outline

A union is the correct solution.

union {
   char* c;
   int* i;
   short* s;
} p;

*p.i++; 

This suggests an excellent model for describing this extension. The lvalue
cast behaves as if the object is a union of two fields.  One field with
the original type and the other field with the cast-to type.
