+1 on that.

Why do you and Matz not like #but_first ? Doesn't that make more sense to split words? #is_a? 
I knew not much of methods that doesn't split words (actually I can remember only #upto and #downto)

----------------------------------------
I propose the addition of a `tail` method to the Array class that returns all elements but the first. It is a pretty common pattern in functional programming, but not limited to - I use it extensively in all kinds of apps/gems. The implementation would be pretty trivial, I won't risk a patch to MRI because I'm uninitiated on ruby core matters, but powerpack gem (http://github.com/bbatsov/powerpack) implements it in ruby in terms of slices.
