Hey people! I got a tech-question for you 🙂
Why do you (:spryker:) have this pattern of returning the Container object in the DependencyProvider (and some other places as well) where you return the same object that you pass as argument WHEN actually objects are passed by reference (not by value)?

If we would talked about immutable objects where we are returning a new (immutable)instance, then it would make sense to return the new object (with the new state), but this is not the case in most of the places I've seen in Spryker (or should I say all of them so far...)  specially this, inside the DependencyProvider.

For me, personally, it seems more like unnecessary boiler-plate code. Or am I missing something here? Thanks!
(I attached two pictures: the current code from ProductDependencyProvider and my example)

    We have the convention: when you pass object to change it, we need to return the same object.

    So in this case it doesn't matter how the function is implemented, maybe it will do (new Class()) or clone $class, but we know that we expect the same TYPE of object.

    mmm I see. Then it's an internal :spryker: convention. All right. Thanks, @UKBTMFXMJ!

    so if you don't like it and don't want to follow this convention - you are absolutely free of choice ;)
