No, Pimp my Library is not an anti-pattern. It even received dedicated syntax with `implicit class`es. Contrary to general implicit conversions, implicit classes are not dangerous because things are not actually <i>converted</i> as far as the developer can see (yes, under the hood, it&#x27;s an implicit conversion, but it doesn&#x27;t bite you). You&#x27;re simply adding methods on existing classes, which is similar to extension methods in several other languages.
