Well, for C++ the backwards compatability is even better. Unless you're using `gets()` or `auto_ptr`, old C++ code either just continue to compile perfectly, or was always broken.
Sure, the Go standard library is in some sense bigger, so it's nice of them to not break that. But short of a Python2->3 or Perl5->6 migration, isn't that just table stakes for a language?
The only good thing about Go is that its standard library has enough coverage to do a reasonable number of things. The only good thing. But any time you need to step outside of that, it starts a bit-rotting timer that ticks very quickly.

No, it seems it's broken way more often than that, requiring manual changes.
But any time you need to step outside of that, it starts a bit-rotting timer that ticks very quickly.
This is not my experience with my own or third party code. I can't remember any regressions I experienced caused by code changes to the large stdlib at all in the last decade, and perhaps one caused by changes to a third party library (sendgrid, who changed their API with breaking changes, not really a Go problem).
A 'bit-rotting timer' isn't very specific or convincing, do you have examples in mind?
