New Array Methods in 1.9.2

Here is a nice summary of the new Array methods in Ruby 1.9.2.  There's nothing earth-shattering or game changing, but there are some nice little additions.  Though to any Lisp programmer out there, this is all old news.  It's hard to avoid comparing Ruby with Lisp (and other similar functional languages) when there are so many methods for dealing with lists (Arrays).
