> Rust is still in a research phase. People are still figuring out how to do certain very basic stuff without a garbage collector. See e.g. how long it has been taking to get a decent GUI library with callback functions that can be closures that reference external parts of data.
Are Golang, Ruby, Python et al still in the "research phase"? After all, none of them have native GUI frameworks written in them yet.
That said, you're moving the goalposts. The entire premise of my original reply was objecting to your claim that Rust paints you into a corner should you need a non-tree-like data structure. Which is absolutely ridiculous, there are countless examples of self-referential datastructures written in Rust. They use unsafe, which is what it's there for.
