Recently I have had the opportunity to write a microservice in Go. It was a very refreshing experience switching from Scala. Go is a lot faster to compile and runs with a far smaller footprint. The channels are nice. On the other hand the testing feels wrong because its so annoying to do mocks. And don't even get me started on the dependency management. Overall Go feels to me like some version compiled PHP with bette…

YMMV, but my experiences with SBCL were way better than with Go. Using Hunchentoot and the other Quicklisp libraries made developing fun again. With Go I had to constantly worry about errors, repeat the same code snippets over and over again, had to comment out "unused" variables just to try something... not fun. That said, let's see how Lisp works out once I cross the 10'000 LOC barrier. But by then it won't be a microservice anymore, anyway...

I really wish that there was a language which had these features: - simple (so not Scala, Haskell, Perl 6, etc.; no Rust either, unfortunately) - clean (nice syntax, preferably Python inspired, but consistent) - modern (generics, some functional features, string interpolation, etc.) - decent concurrency/parallelism story - good IDE, preferably supported by the core dev team - compilation to a (possibly static) native…

Other than the compilation to binary, Elixir seems a good fit for what you're looking for

OCaml seems to match a majority of the criteria, though AFAIK no "good IDE" (tooling like merlin is available, but if you're looking for e.g. a refactoring IDE you're probably SOL), the ecosystem is small, and it does have some historical baggage.

A lot of people I know are bailing on .net because it doesn’t live up to the promises. Everyone else gets the cool stuff first, the vendor that owns it is a dick and there has been so much schizophrenia over the last few years that it’s a business risk adopting it in case you have to throw your product under a bus again. Go is showing itself to be a good compromise especially with the simplified nature of deployment…

I wonder where, in this little corner of the Earth, it keeps being Java and .NET as it has always been the last 20 years.

> compiled PHP with better concurrency support ...and simpler syntax and without the quirks. But that's one of the best descriptions of Go I've seen so far.

Indeed. Go and PHP are at the complete opposites when it comes to quirkiness. And syntactically PHP is at a very noticeable disadvantage.

Java is fine to be honest. It’s a good solution.

Now I’m going to duck for cover!

Believe kotlin (especially kotlin-native) should soon relieve all those itches.

And with the ReasonML frontend there is a much more approachable-for-other-language-refugees syntax to it.

C# actually already has most of that except for "compilation to a (possibly static) native binary", which is really just a convenience for shipping. It's also not really very cross-platform, it's definitely a "Windows First" language.

C# has always had "compilation to a dynamic native binary" since version 1.0 via NGEN.

Mono has always supported "compilation to a (possibly static) native binary".

Windows 8 introduced "compilation to a dynamic native binary" on the Windows Store via the Bartok compiler used in Singularity.

Windows 10 adopted "compilation to a static native binary" with .NET Native, based on Midori compiler toolchain.

The .NET Core team has CoreRT for the same purpose.
