I need some help understand the behaviour of my code[1].
Specifically I have trouble with `add` method on line 79.
My impression is that since it returns `this`, multiple
invocations can be chained like `obj.add(X).add(Y).add(Z)`.
However the test on line 92 fails and if I do a `writeln`, only
"p1" and "p2" records show up.
What am I missing here? Thanks in advance.

You should mark your return type with ref. Structs are value
types and therefore you return only a copy currently.
