Go-1-2-Proposal---Immutability

I’ve a very small working experience with Go, tried it on few personal projects to test the language. Globally I really like it, and I’ve been pleased by a lot of « features » (simplicity, explicitness, readability of the standard lib etc…). One thing that I miss was an immutability story. You have values/references and, again I’m a beginner, I’ve the impression that passing references are favored. Wouldn’t it be nice if the compiler was able to check if you can mutate a reference or not? There are some proposals [1] that are discussed [2], that can be a nice evolution.

Hey guys, I just published the Go 1.x / Go 2.x proposal to "Immutable Types" that I've been working on for the past month and it's now official: https://github.com/golang/go/issues/27975 Please be sure to check it out and feel free to join the conversation! Even if this feature is never introduced to the language specification - reading the design document will make you a better Go developer, that I guarantee! original design document: https://github.com/romshark/Go-1-2-Proposal---Immutability
