struct Test {
   @disable this();
   // This makes it so `Test t;` won't work - you have to use a constructor of some sort

   this(int num) {
        // Construct it using the number
   }

   // `static opCall` makes `Test()` work when you spell it out
   static Test opCall() {
        Test t = Test(1);
        return t;
   }
}

However, when I try to compile this code, it doesn't work, and I get the following error message:

Error: struct `file.Test` `static opCall` is hidden by constructors and can never be called
dlang/source/file.d(72):        Please use a factory method instead, or replace all constructors with `static opCall`.

I am trying to define a struct, and I want to add a default constructor. Additionally, I want to disable the default constructor to enforce the use of of this constructor. I did some research and found that it is possible to achieve this as follows in this link (https://forum.dlang.org/post/zmtssyredfqohwabvlnv@forum.dlang.org):

struct Test {
   @disable this();
   // This makes it so `Test t;` won't work - you have to use a constructor of some sort

   this(int num) {
        // Construct it using the number
   }

   // `static opCall` makes `Test()` work when you spell it out
   static Test opCall() {
        Test t = Test(1);
        return t;
   }
}

I'm wondering if there are any workarounds to make this work? It is not a significant issue as i can use factory method but it would more practical if this worked.
