For what it’s worth it sounds no worse than Java: you have immutable strings but you have no way to enforce that you can’t modify something that you have recieved, which is why the underlying char array for a string has to be defensively copied if the user asks for `asArray()` or whatever it is.

Strings being immutable doesn’t seem like a special case, though. The underlying mutable array is just encapsulated, which is something that you can implement yourself. (But reflection… maybe you can break the rules with reflection.)

No worse, possibly better, yeah. In a fair number of ways I prefer it over Java, e.g. reflection being so limited makes code dramatically easier to understand with confidence, because a large number of common reflection shenanigans in Java simply can't exist at all in Go. The clean slate and lack of inheritance also means the incredible towers of inheritance insanity simply don't exist - it's wonderful.

But I work on a pretty big system. The near-inability to both efficiently and safely abstract things is a big problem, and it'll be years before mature uses of generics truly start to address that... when it even can. Then I miss Java quite a lot. Or maybe more accurately Kotlin. Or sophisticated code generation and bytecode modification. Or MAT. Or...

I don't think you can reflect onto the standard library anymore, with the recent "strong encapsulation".

Java gets a pass because it was early. Go had time to learn from its mistakes and…just refused to do so.
