The following doesn't link:
struct A {}
void main() {
int [A] w;
A a;
w[a]=8;
}
Outputs: Error 42: Symbol Undefined __init_14TypeInfo_S1x1A.

Yes. It needs a typeinfo class for it to work. Unfortunately, I haven't figured out a way for this to work for user defined types. To make it work for now, you'll need to write one, see the ti_*.d files in phobos for reference. They're pretty simple.

Right. That's because a class has the several predefined virtual functions needed.

What is the difference between a TypeInfo and a ClassInfo?

TypeInfo gives information on any type, ClassInfo just for classes.

This seems like an implementation detail that has leaked out. Sean "Walter" <walter digitalmars.com> wrote in message news:bva2mu$3198$2 digitaldaemon.com..."Sean L.
