This is awesome. Clojure has had similar frameworks for a while, but Clojure has a fairly steep learning curve. Really excited to try this in Scala. Wonder if this will be a new trend away from the totally separate webapp + rest API model...
I'm curious why you say Clojure has a steep learning curve.
Most programmers grow up with learning OOP and so throwing all of that out and asking you brain to do everything in reverse is challenging. I know having worked with a dozen J2EE developers in their transition to Clojure. It took at least 3 months to just be productive.
Scala for many people is just Java with a sprinkling of functional and they never really bother to learn the internals or the more complex areas like generic programming e.g. Shapeless/Cats.
Personally I think it's less about FP vs OOP -- even if the OO parts of Scala are familiar, you're going to encounter FP code in Scala, and in general there is a lot more to learn with Scala as a language just to be able to read other people's code effectively.
It's overly engineered with too much clever magic and hence is very reminiscent of frameworks like J2EE Spring which is why people left Java to begin with.
But this compiler plugin makes it infinitely easier: https://github.com/tek/splain
OOP + FP is actually doing quite well, look at Swift, ReasonML (essentially OCaml, which is also doing fine by itself).
I think that's definitely in the eye of the beholder. The overwhelming opinion I've heard from those in the community is that they greatly prefer having the option, but wouldn't want it required. And that's exactly what spec provides. The language isn't perfect (and honestly, what language is, for every purpose?) but calling it a failure is quite hyperbolic.
as is claiming that Scala is a failure. If adoption and widespread use across industries (big data, hardware, server, web, etc.) is any indicator of success, Scala is just that.
The reality is that both languages are excellent; if you work in either for the day job you're fortunate -- there are far worse languages out there.
Agreed, and I admit I didn't see this as a response to 'dustingetz' equally hyperbolic criticism of Scala. Answering hyperbole with more hyperbole is rarely a way forward for constructive discussion.
It's odd that across so many industries companies would adopt an experimental language; it's almost as if Scala was a stable, production ready language, a successful one even, and that some people have opinions, well founded or not.
> Everyone who gets to be any good at Scala eventually migrates to Haskell or Clojure
The number of Scala developers migrating to Haskell far exceeds that of those migrating to Clojure, probably by a factor of 100X.

a resounding success? "There are only two kinds of languages: the ones people complain about and the ones nobody uses." Which of the FP languages at hand do people complain about?[1]
