Hi guys What I would love is the following: that we get a good Complex package! Since we can do method extensions in Smalltalk we can design a really nice Complex packages with its own tests. We could publish for now Complex into PharoTaskForces or create a PharoExternalPackages or whatever. What do you think? Stef
