It sounds like a good candidate for the Inbox, so we can get a better
understanding of our interest.

So I implemented (well honestly it’s a bit of a stretch to call a subclass with one method implementing, but there y’go) ‘DelegatedLayout’ which is a singleton class that just passes the #layout:in: message off to the morph that is the first argument by sending it  #fixUpLayoutIn: {the second argument}. My morphs (that need this policy) then just implement #layoutPolicy to return `DelegatedLayout new`, which returns the singleton instance. After that, they are integrated into the whole #fullBounds/#doLayoutIn: system of updating. I’ve had so very much fun debugging the side-effects of this change, finding an amazing number of recursions and other semantic infelicities.
