undefining `object_id' may cause serious problems

[halostatue]

Hi,
When I use your plugin, I got below notification.
C:/redmine/vendor/bundle/ruby/1.9.1/gems/blankslate-3.1.2/lib/blankslate.rb:51: warning: undefining `object_id' may cause serious problems
You're extracting __|instance_eval|object_id in BlankObject class, though it's needless? When I check document of builder, I thought that. Could you fix this problem?
thanks

I think I'm going to reimplement the necessary bits of BlankSlate in RubyPython and remove it as a dependency, as the issue (and a pull request addressing the issue) has existed for a while: masover/blankslate#7
This will be resolved in 0.7.
