> But then you need to write all the setters, and something that was supposed to be simple, a function, becomes a whole contraption with a bunch of auxiliary code. Personally I would avoid that, and I definitely wouldn't make it a rule of thumb to use builders in every function with more than 2-3 arguments (maybe you meant something else). Yeah, it's tedious, but that's Go for you ;) Rust has the same issue, but there are macros libraries that will create the builder for you based on the struct definition, so it's _very_ trivial to create these builders. You could do the same with codegen for Go, but this always feels much worse to me than using macros for a number of reasons like having to install a separate tool, checking in generated files, making people run `go generate` after some (but not all) changes, etc.
