I've noticed that some systems actually don't create [>~] or [<~], so I
was thinking to redo those sections with [expr~] anyways. If you'd like
to jump in and do all that, it could work. The main part of that chapter
is that it is also covering digital logic, so I wanted to stick with
values of 0 and 1 for clarity. Do you see any way we can work this out?
