What is the current (0.9.1) way to order systems?

[scarlet kettle]

Haven't worked with Bevy in a couple years, what is the recommended/idiomatic way of ordering systems?
i can see .add_stage_after() but IIRC, stages are on their way out so I'm not sure if that's right

There are two ways depending on your use case

oh wait, this will be easier:

1. https://bevy-cheatbook.github.io/programming/system-order.html
2. https://bevy-cheatbook.github.io/programming/stages.html

You can either use labels:

app
    .add_system(other)
    .add_system(mine.after(other))
// or
enum Systems {Other, Bar, Baz}
app
    add_system(other.label(Systems::Other))
    .add_system(mine.after(Systems::Other))
``` which order systems in the same stage, this is (1)

Or you can use stages (2). Which you'd want if depend on the effect of Commands crated in other in mine.
