I have absolutely zero understanding of Finnish (I don't think I've ever
really encountered any before).
> I have learnt that if I say "Travis, open the window", it means that I
have one specific window in my mind and I suppose that you also know what
window I mean. "Open a window" means that there are several to choose one,
and I don't care which one you open.
Yes, provided there is only one window we are discussing.
> In "Return the number of elements in the poset." I suppose that it is
clear what poset we are referring to.
In a way, yes, but it is more precise to say "this poset" as there might
be one more poset around (especially when there is another input of a
poset).
