Hej Tejas,

Sure, here is the code snippet, it resides within a struct
along with various operator overloads.

To be honest, I am not exactly sure what is happening here. I
am unfamiliar with the "(T : T[])" syntax ... need to read
up a bit on that. (However, not so eary searching for a ":")

BR,

// --- cast overloading 
-------------------------------------------
// T[] opCast(T : T[])(){     // this works
    T[] opCast(T[])(){ // yields: "Error: identifier expected for 
template value param"
       T[] x;
       x.length = this.length;
       for( int i = 0 ; i< this.length ; i++){
          x[i] = this.ptr[i];
       }
       return x;
    }
