          Issue ID: 13495
           Summary: DMD fails to call struct constructor with default args
                    when default constructor is @disabled
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: DMD
          Assignee: nobody@puremagic.com
          Reporter: ketmar@ketmar.no-ip.org

i think that calling struct constructor with omited default parameters should be allowed even if struct has @disable this(). i.e. the following code should work:

  struct S {
    int v;
    @disable this ();
    this (int n=42) { v = n; }
  }

  void main () {
    auto s = S();
  }

now compiler complains: "Error: constructor z03.S.this is not callable because it is annotated with @disable". but here is another constructor that perfectly fits.
