> Is it something that can be fixed with editions? My guess is no, or at least not easily.

Assuming I'm reading these blog posts [0, 1] correctly, it seems that the size_of::<usize>() == size_of::<*mut u8>() assumption is changeable across editions.

Or at the very least, if that change (or a similarly workable one) isn't possible, both blog posts do a pretty good job of pointedly not saying so.
