Currently, it is impossible to special-case comparisons with null. If instead
null had its own type, one could allow direct comparisons between user-defined
types and null, instead of supporting comparison with any and all void*s.
For structs, such a comparison function could then be used for both 'foo ==
null' and 'foo is null'. For classes, neither likely makes sense.
