Description Bill Baxter 2009-11-20 15:49:09 UTC 
struct Struct
{
    this(int _n) {
        n = _n; x = 5;
    }
    this(int _n, float _x) {
        n = _n; x = _x;
    }
    int n;
    float x;
}

enum A = Struct(1);  
enum A = Struct(1,2);


Both calls fail.  But if you /don't/ define any constructors then the second one would work.

Additional note: static opCall does work with CTFE.

I have sent Walter a patch for this. This was much more difficult than you might expect.
