I have not used Go generics, but it's viability as a business logic language would depend on that.
- riku_iki 3y agothey have generics now, but there are other conceptual shifts: - no inheritance - error codes with explicit handling everywhere
- mongol 3y agoYes those are also drawbacks

- gabereiser 3y agono inheritance but there are interfaces to be able to provide alternate implementations. Similar to traits in Rust. If it quacks like a duck, has feathers like a duck, swims like a duck… Go just assumes if you satisfy the interface, you’re good.
- riku_iki 3y agomaybe, it is just some effort for someone who coded in classic OO for last 20 years to wrap head around this new concept fast and judge if it will satisfy all/most use cases.
- Kamq 3y agoWait, what? Generic programming is a perfectly valid style, but are you saying it's essential to implement business logic? Because, like, the last 3 languages that got adopted as the default business logic language didn't have them (Java pre 1.5, C, and Cobol).
- riku_iki 3y agoand during last 20 years consensus has converged to the view point that generics are essential.
- Kamq 3y agoHuh. Guess I'm heterodox, then. I mean, don't get me wrong. It's quite useful once in a while, especially when working with containers, but I don't think of it as essential. But I'm fine with it as long as people don't overdo it.
- rerdavies 3y agoRolling your own containers really really sucks. Sucks enough to the point that it is essential, in my books.
- Kamq 3y agoMaybe I should be more clear. This thread was in the context of go generics, which generally means go 1.18, when user defined generics were added to the language. Go always had support for a minimal number of containers, I've never rolled my own when working in the language. Go had special compiler support for slices, maps, and channels before then, and they got used as the default containers for everything. Using those was annoying when you needed to do the same thing to, say, a slice of strings and a slice of ints, but if you aren't using a generic heavy style, it actually comes up surprisingly rarely. And, if I'm being honest, I'd consider most of the uses of generics I've seen the average enterprise dev use to be mistakes.
- mongol 3y agoIt is not essential, but without it, it is much more cumbersome. I programmed it with Java so I know it can be done but I would not choose a language without it if I could.
- xmcqdpt2 3y agoIt is absolutely necessary nowadays, yes. Our applications are often more complex than what people did in Java 1.5, Cobol, or C, and definitely need to be developed at a faster pace.
