If you want a boolean, use

or something.

Definitely or something. Unary ? has the wrong precedence there.
You could write:

I often use [ ] and [X] to represent true and false in text output.
They resemble checkboxes. I don't think printf needs a boolean output
template, but it would

I've ripped out the previous, extremely brittle, test suite and replaced it

Seems insufficiently general. However, I note that booleans are
an enum, and by default stringify to Bool::True or Bool::False.
Maybe %t stands

So far (eep!), the documentation talks about file test operators as
working with pairs, which will be a weird thing to explain, I guess.
I'm wondering if this matters to the mere user at all, and if we should
even talk about them in terms of pairs. I don't want a different set
of terms in the docs
