rest sounds definitely better. Clojure uses it and it feels very natural
and readable.

Issue #9023 has been updated by bozhidar (Bozhidar Batsov).<br>

I also dislike the name Array#tail, since it&#39;s commonly associated with=
 linked lists, not arrays. I think a much better name would be Array#butfir=
st (and I&#39;ve actually renamed Array#tail in powerpack to Array#butfirst=

I propose the addition of a `tail` method to the Array class that returns a=
ll elements but the first. It is a pretty common pattern in functional prog=
ramming, but not limited to - I use it extensively in all kinds of apps/gem=
s. The implementation would be pretty trivial, I won&#39;t risk a patch to =
MRI because I&#39;m uninitiated on ruby core matters, but powerpack gem (<a=
