... It seems to me that backward compatibility is jeopardized in this process (I know it's not a Pharo value, but it is a Squeak one).
<rant> What's up with some people in the Squeak "camp" trying to artificially draw distinctions between Squeak and Pharo - to the point of FUD, like the above statement.
Keep cool, man. I just expressed a fact, and a worry as far as I am concerned, because I do need backward compatibility if I expect muO to grow with Squeak. I have no problem with Pharo project nor people, so please don't create trouble where there is none. This is a technical discussion.
