Yes, and I like it. ;)  The only thing I don't like about it is the
potential interplay with the rest of the type system.  The mapping to a
single type per value is good, but it doesn't completely solve the problem.
I just think it is better to steer clear of the situation altogether.  I
personally only use static const for interface values though and use
enumerations for internal values (with casting if necessary).
