          Issue ID: 21547
           Summary: Oder of constructor declaration affects struct
                    initializer
           Product: D
           Version: D2
          Hardware: x86_64
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd

struct Bar 
{
    @disable this(int a) {}
    this(int a, int b) {}                                                       

    string a;
    uint b;
}

void main ()
{
    Bar b = { a: "Hello", b: 42 };
}

Compiles fine. Whereas:

struct Bar 
{
    this(int a, int b) {}
    @disable this(int a) {}                                                     

    string a;
    uint b;
}

void main ()
{
    Bar b = { a: "Hello", b: 42 };
}

Gives: test.d(12): Error: struct `Bar` has constructors, cannot use `{
initializers }`, use `Bar( initializers )` instead

Expected result: both examples give the same error.

The problem is that the compiler checks the first declared constructor and if
it is disabled it considers that the struct does not have any other
constructors. It should check the entire overload set.
