That's something I don't really get. I totally understand that you can't
instantiate the template during runtime, but why can't already
instantiated classes be registered just like non-templated ones?
I tried the following snippet, and couldn't find C!int.C anywhere,
although it **must** be there: I can get the `TypeInfo_Class` object, so
I can clearly create new instances at runtime:
```d
import std.stdio : writeln;
class C(T) {}
class D {}
void main() {
auto c = new C!int();
auto c2 = typeid(c).create();
auto d = new D();
writeln(typeid(c).name);
writeln(typeid(c2).name);
writeln(typeid(d).name);
writeln("----");
writeln;
writeln;
foreach (m; ModuleInfo) {
if (m) {
writeln(m.name);
writeln("--------------------");
foreach (c; m.localClasses) {
if (c) {
writeln(c.name);
}
}
writeln;
}
}
}
```
