At least it is better than Java's instanceof + cast. Except that in a language with generics you have to cast far less, so it is no surprise that Java is less

At least it is better than Java's instanceof + cast.
Except that in a language with generics you have to cast far less, so it is no surprise that Java is less optimized for type casting.
