Persistent Collection VS hylo

So does Java! Also, kotlinx.collections is still not stable and I don't think they are intending to make it so any time soon.

> If you are using containers, always, always, always use immutable containers from Google Guava unless you have an exceptionally good reason.

I actually prefer pcollections: https://github.com/hrldcpr/pcollections

AtomicReference + immutable data types is a really nice way to program in Java, and is basically the way most Clojure programs are written.

You might consider persistent collections instead of immutable collections, I believe it is more optimized https://github.com/hrldcpr/pcollections

Or Val[0], now called Hylo (for a good reason), or V[1].

The evolution of C++ has been a multi-decade history of dealing with difficult reality.

I have great hope that Herb can create with his cppfront project “The Very Best of C++” to carry that tremendous legacy forward.

If I was to throw my hat into a “C++ successor”, it would be https://www.hylo-lang.org/ with its “all the safeties” and “tell you when you’re doing it sub-optimal” approach.

> Hylo is a language for high-level systems programming that promises safety without loss of efficiency. It is based on mutable value semantics, a discipline that emphasizes the independence of values to support local reasoning. The result—in contrast with approaches based on sophisticated aliasing restrictions—is an efficient, expressive language with a simple type system and no need for lifetime annotations.

> Safety guarantees in Hylo programs are verified by an abstract interpreter processing an intermediate representation, Hylo IR, that models lifetime properties with ghost instructions. Further, lifetime constraints are used to eliminate unnecessary memory allocations predictably.

A model without lifetimes is also being explored in other languages, e.g. in Hylo. It sacrifices expressiveness, but on the other hand you don't have to deal with explicit lifetimes!

Why go through all the trouble when you can do this: https://www.hylo-lang.org/ and not spend a second thinking of lifetimes? No, copies will not be issued unless necessary.

Or why not keep exploring this idea as well? More research-oriented than the first one right now, though, so take it with a grain of salt: https://vale.dev/

Get rid of references at the cost of some expressivity (see Hylo, formerly Val)
