No worries. As you said - it's a low frequency operation so it's not a major issue. Maybe I'll have a look at optimising it, though I'm not a rust...

Thinking about this more, we can do something like `Fn`/`FnMut` in the standard library: * Provide `MapEntities` and `MapEntitiesMut`, with a blanket `impl MapEntitesMut for T` * Rename all current...

Whoops, didn't think I'd need to run the lints...
