@bagder Well, 018 isn't legal octal so it can only reasonably be interpreted as decimal or an error

@RandomDamage @bagder I'd argue, as long as the 0-prefix is interpreted as octal (which in and of itself is a terrible footgun that never should have happened), the only reasonable interpretation should be an error. And not just any error, an explicit "invalid argument" error and none other.
