This implementation doesn't support the select statement.

The syntax is nice, pattern matching, traits and generics are nice. The added value is a language with a better type system than Go in Go's space (web development). I don't want manual memory management or to have to care about regions, lifetimes or borrowing.

Go is describes itself as "a dumb down language", because according to Rob Pike, "young engineers at Google are too stupid to understand C++ or Java" or something like that.It's true you can learn it in 3 days and be productive with it.

Learning D and Rust requires an effort Go proponents are not capable of.

Another problem is that both D and Rust try to replace C++ and C respectively. But C++ and C developers would never switch to anything else as they feel comfortable using the later, even despite all the gotcha of manual memory management.

Most people using Go today come from Python,Ruby,PHP,JS and co, not from C or C++ or Java. They want performances, without paying a price for "complexity". D is fine today, but it lacks a community behind it and a good ecosystem for web development.

If Rust had garbage collection, it would certainly be more popular but it's not going to replace C anyway. We are stuck with C and C++, they are not going away.

I understand why Rust is what it is, I also understand that most developers don't want to deal with explicit move semantics and lifetime management. Rust isn't going to seduce Ruby,Python,PHP or Javascript developers. the later only want better performances and think Go is good enough. They don't care about explicit memory management.

I'd like to see a version of Rust with garbage collection. The language itself is good.
