The way that you can turn normal Rust functions into systems, grabbing the relevant components through their type signature is wonderful sugar, and feels magic to use.

That's the level of Rust I wish there were more learning materials about.

I tried to make sense of the tutorial with various degrees of success :) Does this mean the components get automatically iterated over in no particular order (for instance the Persons in the example)?

[PudgePacket]

That's correct.
