The documentation says "To overload a[], simply define opIndex with no parameters":

And it works with some uses of a[]. However, opSlice() seems to be needed to actually use the returned slice further.

Note that opSlice() also seems to be for backward compatibility: "For backward compatibility, a[] and a[i..j] can also be overloaded by implementing opSlice() with no arguments and opSlice(i, j) with two arguments, respectively. This only applies for one-dimensional slicing, and dates from when D did not have full support for multidimensional arrays. This usage of opSlice is discouraged."

How can I achieve the last line in main() without needing opSlice()? I am trying to let the Slice type handle opAssign() and friends.


--8<-- snip --8<--

    // This requires opSlice.
    c[] = 42;
}

Have you tried opIndexAssign()?
