My thoughts on his points, from someone who really likes Go and has used it heavily on small and large projects (1M LoC):<p>1. Probably a matter of taste, but I love this feature, just because of the lack of noisy public/private keywords everywhere that you see in Java et al. It also means you can tell from a usage (not just the definition) that something is exported, which is often useful.<p>As far as renaming goes, either rename the definition and see where the compiler complains, or get your IDE to do it (I use GoLand, but good things are said about gopls).<p>As for his example, the idiomatic way to write that is either just call it `usr` or `adminUser`, or use `user := &user{}` which is valid (if a little confusing).<p>2. This is a <i>feature</i>: it allows you to define interfaces only where you need them (on the consumer side), and you define the interface with only the methods you actually need. This means that when you add a bunch of new methods on the implementation, you don't need to change all the consumers. Go interfaces are amazing.<p>The downside he discusses almost never happens: it's surprising, but even in large projects I've never had structs accidentally implementing interfaces or a IsAdmin method being implemented with reversed polarity by accident.<p>3. Definitely has its downsides. Tooling helps find unchecked errors. Though I've found the biggest downside to explicit errors is the verbosity. You do get used to it, and the explicitness is at least clear.<p>4. There are a couple of "magical" things like this, but they're well known and documented, and simple to fix if you run into them. I love the fact I can just name a file foo_test.go and add TestFoo methods, and "go test" finds them automatically.<p>5. I have not found this to be the case, and in the rare cases it does happen, the compiler tells you loudly and it's easy to fix.<p>6. Yeah, this is a slight pain, but the semi-official "imports" package (golang.org/x/tools/imports) fixes it up, so you just run generated code through that (and it auto-formats the code as well). It's a couple of lines of code. See: <a href="https://github.com/benhoyt/prig/blob/2df1b65a2bdf34c10bb5e57ecc99d1775bc9d196/prig.go#L134" rel="nofollow">https://github.com/benhoyt/prig/blob/2df1b65a2bdf34c10bb5e57...</a><p>7. Yeah, I wouldn't mind a ternary operator. Easily misused, which is why they didn't add it, but it would be really nice used judiciously, rather than the 4-line if-else block.<p>8. Fixed by sort.Slice, which avoids the need for Len and Swap (and even more so by the new generics "slices" package, coming soon). I guess this was added after the article was written?<p>9. Fixed by "Go modules", which is really well designed and works well (though opinions differ).<p>10. Fixed with generics being added in Go 1.18. And generic helpers like "slices" and "maps" packages coming soon.<p>11. Yeah, slightly annoying for newbies, though as he mentioned, tooling tells you. I do like the control you (can) get over allocation and memory management with Go slices.<p>As far as his summary goes (eg: the type system getting in your way for large programs), I have definitely not found that to be the case. The author doesn't like Go, and that's okay! I don't like Java. :-)
