Personally, I love Pony and use it in a "background" project meant for RaspberryPi-level of embedding.
Yes, steep learning curve, but the pay off is huge. When it compiles, I can be (almost) sure that there are no concurrency related bugs.
Article doesn't mention the excellent C interop in the language.
Call C natively;
let world = "world"
\@printf( "Hello, %s".cstring(), world.cstring() )
The ampersand makes it a C call, and the cstring() is needed for strings.
