Adding/Removing components with ForEach

So ForEach is the new kid in town for doing chunk iteration in a simple way. And it works reasonably well if all you do is modify component values. However I quite often have the requirement to add or remove components:

Code (CSharp):

1. public void OnUpdate() {
2.     ForEach(entity -> {
3.         PostUpdateCommands.AddComponent(entity, new SomeComponent());
4.    }, someComponentGroup);
5. }

This works however it creates an allocation for `this` all the time. Currently I solve this by doing manual chunk iteration, but this is creating really noisy code with those nested `foreach` loops and the other boilerplate that is required for chunk iteration. Is there a better way of doing this?
