The error message is gone, but I now have another compilation

This is what I have in fact
interface Info { . . . }
class MyInfos {
. . .
protected:
class Obj : Info
{
. . .
}
public:
static immutable Obj one = new immutable Obj(...);
static immutable Obj two = new immutable Obj(...);
}
I get a compiler error in the two assignments to the static Obj
member variables:
'this' is only defined in non-static member functions, not
MyInfos
Is it related to the fact that the Obj class is encapsulated ?
Yes, nested classes have an implicit reference to their parent
object, which doesn't exist in your case.
My goal is to be able to write things like this:
void main() {
Info x1 = MyInfos.one, x2 = MyInfo.two, x3;
assert(x3 is null);
x3 = x1;
assert(x3 is x1);
assert(x3 is MyInfo.one);
// Use static immutable instance references as case arg in
switch
switch(x1) {
case MyInfo.one: ...;
}
}
It looks like your don't actually need `Obj` to be a real nested
class. Try declaring it as `static Obj : Info { }`. This should
work if `Obj`'s methods don't need access to `MyInfo`'s
non-static members.
