[MacRuby-devel] When is a String not an NSString?

[Thibault Martin-Lagardette]

In fact, there's already a track ticket for that (and I think that's the discussion Laurent was looking for):

If you want a method to be available to all strings, add it to the NSString class. I do agree that this can be confusing behavior and maybe we can try to reduce the confusion somehow. This design was implemented in 0.6 and is the result of several debates. I personally didn't expect people would notice this :)
