several questions on using gems

SWIG and Arrays (of ints)

+ 121471 [ruby@br an s] I'm polishing my solution, and I'm wondering why you are storing object id's instead of object references in the tree? I'd imagine that storing the object reference takes the same amount of space as storing the id. Is it maybe because objects can't be GCed while they are stored in the tree? On the other hand, wouldn't GCing break your program?
  121640 [jamis_buck@b] Well...quite possibly this was due to my massive inexperience with

[Solution] Object Browser (#8)
121093 [ruby@br an s] Thanks for the quiz. I always wanted to learn more about the reflection capabilites of ruby, and indeed there is quite a lot to learn. This quiz was not too complicated, but the design of a good gui takes a lot of time. (Especially if you're not accustomed to the toolkit).

  121399 [ruby@br an s] I'd say with all your contributions your ego should be floating quite high ;)
