I've been observing in some stronger critics about Rust a persistent focus on OO features, usually the ones that programmers tend to rely upon and which they feel to be "lacking" in Rust - usually requiring a different structure or abstraction which the programmer is not familiar with. The issue about parent/children pointers mentioned in this article seems more a lack of understanding on the concepts of ownership and the traits system, for instance. It's indeed a harder problem to deal with in Rust if trying to apply a OO mentality, but one can find a way out if trying to understand the language first. I have my personal thoughts about parts is Rust that could be improved; nevertheless, I don't see any issue with us excursions, and consider it an evolutionary step which brings system programming languages to a new level.
