There was a problem hiding this comment.
Isn't this missing a blanket impl for ReadOnlySystem for functions that take &World?
Ideally this would also be implemented for all systems where all of the parameters are read-only as well, but until we can actually make queries via &World this isn't going to be super useful either way.

This trait is implemented for any function system whose parameters all implement |

Oh I see! The trait already existed. Fantastic, thank you :) |

Objective
Resolves #7558.
Systems that are known to never modify the world implement the trait
ReadOnlySystem. This is a perfect place to add a safe API for running a system with a shared reference to a World.Changelog
ReadOnlySystem::run_readonly, which allows a system to be run using&World.
