[MacRuby-devel] Warnings about removing methods

Sure. But first of all, it _isn't_ a pure objc method, it's a Ruby  
method, so not sure when/how this gets classified as a pure objc method…

Second, the worst thing that can happen (afaik) is that the code  
breaks because you removed a method.
And that _should_ break IMO, because that's how Ruby is crafted. So  
it's the developers responsibility
to not introduce bugs in the application code, _not_ of the language/ 
bridge developer.
