Re: Immutable objects and constructor ?

[chmike via Digitalmars-d-learn]

The error message is gone, but I now have another compilation 
error message I don't understand.

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 ?


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: ...;
   }
}
