"filter" is incredibly useful, and most modern languages (including Java 8) have it built in.
"even?" is sometimes useful, and languages are kind of hit-and-miss about it, but its usually small enough to inline, and the biggest cost of not having it built-in is probably things like people using modulus rather than first-bit testing in Java which, IIRC, produces somewhat slower code for that check.
