Agreed, it appears that since they changed to early release their have become pressured to add new language features every year.

As polyglot I have the advantage that I don't have to sell myself as XYZ Developer, and increasingly I don't think C# (the language itself) is going into the direction that I would like, for that complexity I rather keep using C++.

Just wait for when extension everything, plus whatever design union types/ADT end up having, and then what, are they going to add on top to justify the team size, and yearly releases?

Despite my opinion on Go's design, I think the .NET team should take a lesson out of them, and focus on improving the AOT story, runtime performance, and leave the language alone, other than when needed to support those points.

Also bring VB, F# and C++/CLI along, this doesn't not have to be C# Language Runtime, where it gets all the features of what designed as a polyglot VM.
