i am inviting you to think for yourself, to derive them from first principles
and thus be able, if there are any... unusual circumstances, to not be either
frozen solid or disruptive.

be prepared to have to run "killall xdot".

if you at least run "show top" and also inspect submodules visually ("show
presstabkey presstabkey") and if you can relate what you see back to the actual
code and still follow the graph, the design is "clean".

if however you cannot see the graph even at fullscreen because boxes are too
small even on a 1920x1080 screen, then something is wrong, you need to break it
down into smaller submodules.

if possible.

or in this particular case, redesign it.

but not right now.

write unit test first.

research examples on how to do that ok?
