          Issue ID: 20842
           Summary: Structs with disabled default/copy ctors can't be
                    initialized
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: snarwin+bugzilla gmail.com

The following program fails to compile with DMD v2.092.0:

---
struct A
{
    int i;
     disable this(ref A);
}

A a = { i: 123 };

struct B
{
    int i;
     disable this();
}

B b = { i: 123 };
---

The compiler gives the following output:

---
onlineapp.d(7): Error: struct `A` has constructors, cannot use `{ initializers
}`, use `A( initializers )` instead
onlineapp.d(15): Error: struct `B` has constructors, cannot use `{ initializers
}`, use `B( initializers )` instead
---

The expected behavior is for  disabled copy and default constructors to forbid
only copy initialization and default initialization, respectively, rather than
forbidding all initialization.
