You could have done that in Rust but you wouldn't, because the allure of just typing a single character of

    ?

is too strong.

The UX is terrible — the path of least resistance is that of laziness. You should be forced to provide an error message, i.e.

    ?("failed to create file: {e}")

should be the only valid form.

In Go, for one reason or another, it's standard to provide error context; it's not typical at all to just return a bare `err` — it's frowned upon and unidiomatic.
