I was thinking of the case where the caller invokes it by accident (due to incorrect code, e.g. `"..." + hexFormat`
instead of `"..." + hexFormat.toHexDigits(...)`) and then wonders what "uppercase: true, ..." means or where it even
comes from. For example `java.util.Optional` also includes "Optional[...]".
