Other vendors have proven that it’s possible to do this well. Ruby, for example, takes it to the other extreme: their Integer objects respond to methods like #odd?, #even? and even #gcd. Providing those methods in the standard library yields more readable code and it gives the vendor the opportunity to tweak and optimize them at later date, knowing that anyone who needs them will benefit from their optimizations.

Gotta love good old Ruby.
