I see, I haven't tried with 0.4. Maybe the problem is fixed in trunk :-)

I've reproduced it using 0.4, for whatever that's worth. If you open
a builtin class (e.g. NSSet) with the class keyword, the object_id
changes. If you open it with class_eval, the object_id is unchanged.
Best,

Just open them as you would do in Ruby.
Consider, the following where Cell is an ObjC class:
irb(main):001:0> Cell.object_id
=> 4387749088
irb(main):002:0> class Cell
irb(main):003:1> def whee
irb(main):004:2> p 'whee'
irb(main):005:2> end
irb(main):006:1> end
=> nil
irb(main):007:0> Cell.object_id
=> 4388625216
I would expect the object_id to stay the same, e.g. using pure
MacRuby:
irb(main):010:0> class Bar
irb(main):011:1> end
=> nil
irb(main):012:0> Bar.object_id
=> 4298834304
irb(main):013:0> class Bar
irb(main):014:1> def drink
irb(main):015:2> p 'tasty!'
irb(main):016:2> end
irb(main):017:1> end
=> nil
irb(main):018:0> Bar.object_id
=> 4298834304
It's indeed strange. I can't reproduce this on the command-line
using NSPredicate.
$ ./miniruby -e "p NSPredicate.object_id; class NSPredicate; def
hey;end; end; p NSPredicate.object_id"
140735073102888
140735073102888
Normally the class shouldn't change if it's just re-opened.
Do you see the #whee method in Objective-C land once you patch it
from Ruby?
