What sort of internal .system calls do we have left that won't be cleaned up by #2446?

Hahah, I'm sitting on a very similar changeset. Couple differences: started on updating the docs and removed IntoSystem from the prelude, which soft-deprecates it. Wanted to also rewrite make_parallel!() into less of an atrocity.

Code that tests if a function is a system.

Ended up doing that to remove the macro, but there's still an issue: system dependency cycles now stack overflow instead of panicking

I have no idea why that's happening... Have to sleep first, I guess.

there was an infinite loop of two traits calling each other name method that needed a .system() to return something concrete at some point, fixed 👍

53 .system() now!

Ah, yeah: that's not the .system() that needs to be removed, it's just named the same way. Weird it didn't come up sooner.

Well, don't mind me...

proceeds to sneak in .system() in every doctest

This re-adds AppBuilder (now that we've removed it on main). Can you remove it?
