Delegator#methods should accept the singleton flag argument
In the new version of delegate.rb
does not accept the "also_declared_on_class" argument, which causes failures for libraries that call Object#methods with an argument and therefore excercise this functionality.
On a sidenote, Object#methods somehow is not documented for 1.9 - but maybe I looked in the wrong place?
This is probaby relevant for rubyspec as well so I've filed it under https://github.com/rubyspec/rubyspec/pull/55
If the idea is to remove Object#methods or Object#methods with arity of 1 only it would be good to drop it on Object as well so that explosions are louder and the relevant calling code is fixed asap.
