Rails' ruby script/console has tab completion!

While I recently found out about Ruby's 'methods' method, I also found that Rails' "ruby script/console" will do tab completion:

>> a =
=> []
>> a.
Display all 157 possibilities? (y or n)
a.fetch a.method a.slice
a.__id__ a.fill a.methods a.slice!
a.__send__ a.find a.min a.sort
a.all? a.find_all a.nil? a.sort!
a.any? a.first a.nitems a.sort_by
a.assoc a.flatten a.object_id a.split a.flatten! a.pack a.subclasses_of
a.b64encode a.freeze a.partition a.sum
a.blank? a.frozen? a.pop a.suppress
a.class a.gem a.pretty_inspect a.taguri

a.encode64 a.last a.send a.values_at
a.entries a.length a.shift a.with_options
a.eql? a.load a.silence_stderr a.yaml_initialize
a.equal? a.silence_stream
a.extend! a.silence_warnings
a.extend_with_included_modules_from a.max a.singleton_methods
a.extended_by a.member? a.size

Unfortunately the same thing doesn't work for the irb. Of course you can always


to see the same information.
