I mentioned about fragility just because that will be an issue for Ruby 2.0. For MRI replacing core methods affect less, just because core functionality is done by C functions. But implantation like Rubinius suffers more. I think we will soon need to start discussing separating/protecting core implementation from user code by some kind of namespaces or packages. matz.
