I think that's the thing that really gets me about Go. I really like that it's opinionated and forces you to write good code, but I just can't understand why they refuse to allow you to turn them off when you need it.

Also doesn't that workaround completely nullify all the arguments they made in that section? And it puts the programmer in a worse position than if they could just turn it off temporarily.




"I just can't understand why they refuse to allow you to turn them off when you need it."

The answer to this and a lot of similar such questions about Go is "scale". Things that were sorta kinda convenient for you in a couple hundred lines become nightmares when several dozen developers on several hundred thousands lines of codes had differing ideas of what was convenient for them at the time.

Just as you can't understand Erlang until you understand its emphasis on reliability, you can't understand Go until you understand its emphasis on coding at scale. Almost (but not quite) everything people can't understand about Go are things that people want to do because they work well locally, but things that have become serious problems in source code bases at scale. You also can't understand Go until you realize that the problems weren't merely hypothesized, but extracted from real already-existing source code bases.

That said, I still feel they missed some steps. I'd like non-nil-able pointers. (Optional, like C#, because the way Go methods work means that if you're careful nil pointers of a certain type are perfectly legal and can have sensible methods on them, but that's not always the case.) Packaging is another obvious case where Google had an answer that worked for them so they didn't see a problem, though that's being worked on. (I'm struggling through this because I consider it a non-negotiable feature that my packaging solution allows me to locally mirror everything I use, which all packaging systems (not just Go!) seem to consider some bizarre use case. Strange, I consider it a basic requirement for truly professional development.) So bear in mind I don't mean this necessarily as a defense of Go, I'm talking about what it takes to understand it.

(Edit: also, yes, I consider it a bit sad that Go doesn't have iterator support, per my comment at https://news.ycombinator.com/item?id=12210351 You can sort of bash some stuff together, and io.Writer and io.Reader cover a common case for Go programs and can be composed, but it's still a bummer.)

It is completely the case that some people will come to a greater understanding of Go, and realize it's the wrong choice for their problems. But perhaps it will, at the very least, be less threatening that other people do consider it a good choice for their problems.
