You can overload opBinaryRight:
MyClass opBinaryRight(string op: "+")(MyClass rhs)
{
if (rhs is null)

return null;
}
MyClass result = new MyClass(value + rhs.

Is there an equivalent to std.range.chunks that will work on a

of code points?

I guess this is also true of insertAfter and co? Should they
