I think this should be no error?

void main()
{
    uint[10] arr1;
    ulong idx = 3;
    //uint[] arr2 = arr1[ idx .. idx + 3 ]; // Error if with compiler switch -w 
    uint[] arr3 = arr1[ cast(int)(idx) .. (cast(int) idx) + 3  ]; // OK
    uint[] arr4 = arr1[ cast(int) idx  ..  cast(int) idx  + 3  ]; // OK
    uint[] arr5 = arr1[ cast(int)(idx) ..  cast(int)(idx) + 3  ]; // C style
cast illegal, use cast(idx)+3
    uint[] arr6 = arr1[ cast(int)(idx) ..  cast(int)(idx  + 3) ]; // OK
}
