I don't have the time to read the whole thing right now and it's a first time I'm seeing Chapel, so I may be wrong.
After skimming the page it looks rather similar to Nim. Chapel looks like it wants to be a systems programming language with special focus on concurrency and parallel computation. It's statically typed with local type inference. It supports product types with tuples, but I don't see sum types or (G)ADTs in general. It has numeric types with explicit range, like Ada or Nim (that is without dependent types). It supports generics, with a very lightweight syntax (ie. lack of any syntax). Supports in/out/inout parameters like C#. Supports operator overloading. Has iterators. Supports class-based OO with destructors (so probably is not GCed?). Has coroutines as a main concurrency construct. It has "sync" keyword, but I don't have the time to look at it in depth to know how it works.
It looks like it's somewhere between C and Java, like Nim, Rust and a couple other languages. From a quick glance I can't tell if the language is garbage collected and I don't really know how the concurrency and parallelism really work in the language. Still, it looks rather nice and I suspect you'd use it any time you otherwise use C with pthreads.
