          Issue ID: 12587
           Summary: Ommiting type when auto declaration in static members
                    results in error
           Product: D
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: DMD

struct S {
    this(int) { }

    static immutable s = S(12);
}

void main() {
}

Error: cannot create a struct until its size is determined

If static immutable s = S(12) changed to static immutable S s = S(12) compiles
ok.
