But I can't help but agree with a lot of points in this article. Go was designed by some old-school folks that maybe stuck a bit too hard to their principles, losing sight of the practical conveniences. That said, it's a _feeling_ I have, and maybe Go would be much worse if it had solved all these quirks. To be fair, I see more leniency in fixing quirks in the last few years, like at some point I didn't think we'd ever see generics, or custom iterators, etc.
The points about RAM and portability seem mostly like personal grievances though. If it was better, that would be nice, of course. But the GC in Go is very unlikely to cause issues in most programs even at very large scale, and it's not that hard to debug. And Go runs on most platforms anyone could ever wish to ship their software on.
But yeah the whole error / nil situation still bothers me. I find myself wishing for Result[Ok, Err] and Optional[T] quite often.
The go language and its runtime is the only system I know that is able to handle concurrency with multicore cpus seamlessly within the language, using the CSP-like (goroutine/channel) formalism which is easy to reason with.
Python is a mess with the gil and async libraries that are hard to reason with. C,C++,Java etc need external libraries to implement threading which cant be reasoned with in the context of the language itself.
So, go is a perfect fit for the http server (or service) usecase and in my experience there is no parallel.
I believe it’s the only system you know. But it’s far from the only one.
I'd love to see a list of these, with any references you can provide.
