This is an anti-pattern IMO and requires an import to opt-in (by the author, not the caller IIRC). Instead you&#x27;d use an implicit value class which should be zero overhead.<p>But that&#x27;s just about the definition, not what it&#x27;s doing which is no good. Anyone can abuse a lot of these features, which depending upon who you&#x27;d ask, is better flexibility than not having them at all.
