What does casting to void do? Does it just ignore whatever

I don't know where you can find this in the docs, but what
doesn't seem trivial about it? The type of the expression
`print()` is void. That's the type that `doSomething`

Ooh that indeed seems useful. Thanks for the hint.
Also slightly off topic, but when

I had no clue, never seen it used in any case. I've always
assumed one couldn't return void as it's not a value. I guess
intuitions aren't always universal . Good to
