But I think I see what you mean, and maybe Purr Data has implemented something similar. They have this [ab] object. For reference: "The [ab] object is accompanied by a number of supplemental objects (abinfo, abdefs, abclone) which let you inspect and clone private abstractions. There’s also an “Abstractions” dialog which can be accessed via the Window menu. This will give you a quick overview of the private abstractions contained in a patch. Also, it will show you private abstractions which aren’t currently being used (i.e., don’t have any instances), so that you can select and then delete them if they aren’t needed any more."
