If Eliot has a plan to introduce "everything is-a compact-class" then it sounds like we get cake and eat cake, we just have to be patient around waiting for cake, or find actually useful ways to help make cake, like getting the baker coffee or something. Compact vs. non-compact confused me too, but I have this crazy idea that everything is going to be okay:)

No. its nothing to do with performance. It is about getting rid of

Well, if fixing it makes Cog slower, then it *is* about performance.

Just making everything uncompact without changing the image format
doesn't really buy us much: it would make Cog slower and the image
bigger with no benefit. The benefit comes from having a new image
format that is optimized for speed rather than space - getting rid of
compact classes would just be a side-effect of the new format.

And interestingly, Eliot's proposal for a new format actually gets rid of the class pointer and makes "everything" a compact class.
