Looks good to me, but I'm not super confident in my ability to judge this code.
| /// Function pointer implementing [`ReflectResource::reflect()`]. | ||
| pub reflect: fn(&World) -> Option<&dyn Reflect>, | ||
| pub reflect: for<'w> fn(FilteredResources<'w, '_>) -> Option<&'w dyn Reflect>, | ||
| /// Function pointer implementing [`ReflectResource::reflect_mut()`]. |

It would be cool if this could be a static assertion

I'm not quite sure what you want asserted? I was trying to copy the style of the existing comments, and I think that's meant to be read as "ReflectResource::reflect_mut() invokes this function pointer".

Objective
Support accessing resources using reflection when using
FilteredResourcesin a dynamic system. This is similar to how components can be queried using reflection when usingFilteredEntityRef|Mut.Solution
Change
ReflectResourcefrom taking&Worldand&mut Worldto takingimpl Into<FilteredResources>andimpl Into<FilteredResourcesMut>, similar to howReflectComponenttakesimpl Into<FilteredEntityRef>andimpl Into<FilteredEntityMut>. There areFromimpls that ensure code passing&Worldand&mut Worldcontinues to work as before.Migration Guide
If you are manually creating a
ReflectComponentFnsstruct, thereflectfunction now takesFilteredResourcesinstead&World, and there is a newreflect_mutfunction that takesFilteredResourcesMut.
