[Pharo-dev] [Reflectivity] Object invalidate now works

Hi, The mechanism that is behind the MetaLinks is now working for Object 50378: Object methods do: #createTwin. Object methods do: #invalidate. This means we are very close on having that working on the whole image. Next steps: -> invalidate the whole kernel. -> then: check/fix putting links on all methods (#before/#after). (there seems a bug in the code dealing with primitives, to check) -> then: meta-recursion stopping links: take care of the code executed until the recursion check is reached. Test. -> First use case: Breakpoints, with IDE integration. Marcus
