Yeah, GemStone/Smalltalk does that - they have a collection of SymbolDictionaries (aka SystemDictionaries) and you can rearrange them, changing the order that an objects' messages traverse through them: dynamic inheritance. Useful for testing out variations and prototypes, but can make your head spin. I know namespaces are an inevitability, but I'll miss just having the one #Smalltalk.

Why not try it on an image near you? Really - I mean it, on an image 'near you', not your own image - surprise a fellow smalltalker : )
