Yes. All we need is a well-documented model that can be made to work.

That's pushing it. I *might* get away with requiring that for my

Do you really mean "not allowing", here? The use of static members in
templates (known to probably not be shared) is one of the primary ways I
get around the problems we're discussing. I routinely declare static
reference members and initialize them through function calls to my shared
library. Once static initialization is done, they all refer to the right
piece of data. If I couldn't do that, I'd be royally shafted.

Right. Also, let me point out that exceptions and RTTI deserve special
treatment because workarounds like the one described above are not
