BeOS & Derivatives "The primary intention of my previous article was to make it very clear why and when locking is needed in multithreaded applications. In this article, I want to present my experiences in writing a new prototype for a replacement of the document model in WonderBrush and how it is manipulated and rendered asynchronously."

You clearly have a pet language, so this discussion is kind of pointless,[q]

I don't have a pet language. I just like modern languages with an orthogonal feature set and decent reflection capabilities. C++ has neither.

I used scala as an example of such a language. But any other language with a) pattern matching and b) strong support for immutable data structures would do just fine. For example ocaml or even plain old standard ML.

[q]The thing is, all of this is trivial and no more difficult or error prone than any other form of procedural programming.

So you are saying that writing 10 LOC is no more error prone than writing 1 LOC?

Don't get me wrong here: I used to love BeOS, and I even think that using C++ to write the core OS parts of Haiku is a good idea. I also do not want to criticize the author of that article. But I sincerely think that C++ is a very bad choice as a language to write multithreaded applications.

Or whatever non HLL. We got it. Thanks.
Now, whatever the language, designing applications that scale well both on responsivness and computing raw power needs developers used to threading design patterns.
No language will know better than you what and where in your application it matter more to use parallelism and where it make no sense at all and, worst case, could even be counterproductive.

Parallelism doesn't oppose procedural language but sequential programming. Two different things. Some language can have built-in parallelism support, sure. And? Doesn't make any threading design pattern article automatically useless.
