I will explain that by opening a new issue.

The implementation of the default constructor should be prohibited as the
current situation. Also the implementation of the default opCall (static ...
opCall()) should be prohibited. And implementing a non-default constructor or a
non default opCall should not cause the removal of the defaults.

------------------------------
struct S {
  ...
  this() { ... } // should give error
}
------------------------------
struct S {
  ...
  static S opCall() { ... } // should give error
}
------------------------------
struct S {
  ...
  this(int a) { ... }
  static S opcall(double d) { ... }
}

S s = S(); // should work
S* s = new S(); // should work
------------------------------

Is this proposal causes a problem like you have depicted? Probably I could not
understand your case.
