Array#abbrev depreciated?

If you look at the core ruby doc, it says Array#abbrev will let you do
this:

%w{ car cone }.abbrev #=> { "ca" => "car", "car" => "car",
                                "co" => "cone", "con" => cone",
                                "cone" => "cone" }

But if I try this in IRB, I get:

irb(main):002:0> %w{ car cone }.abbrev
NoMethodError: undefined method `abbrev' for ["car", "cone"]:Array
        from (irb):2

Is Array#abbrev depreciated?

require 'abbrev' # it's in the stdlib, not core

Yes, ruby changed accountants, and the new accountants have decided to
depreciate abbrev over the next five years for a tax write off.

I didn't realize that a class from the core library would have methods
from the standard library. I know ruby classes can be extended, but I
just didn't expect it here.

Thanks!

I wish this would be obvious from rdoc/ri documentation.
