Yes, but timeIt needs to be simpler. So it's a different purpose.

I don't understand. Generally I don't like ref arguments, they don't allow me
simple usages as:

37.fibonacci.timeIt.writeln;
37.fibonacci.timeIt[1].writeln;

Usually ref parameters require more code, and more cognitive burden. Tuples are
usually winners over most alternatives.
