Likewise, the compiler already ensures that the vtable for a class is
defined only once in a program (cfront-based compilers typically define
the vtable in the same translation unit defining the first virtual
function of a class.)  Could a similar mechanism be used for defining
constants?

PMFJI,

I've been following this thread for a while (but not, obviously, from
the beginning), and I don't understand why you guys aren't using the
"enum hack" to simulate a class static constant?

Because that's what it is, a hack.
