Yes, but only recently. The most notable example in a top company is Facebook's spam detection service, powered by their library called Haxl[0]. The language allows some very skilled programmers to build this library that makes it very easy to write spam rules. Lower-level engineers can then write very simple and elegant code that looks sequential but is automatically parallelized by the library.

The service is a big deal, because every action or request that anyone makes on Facebook touches this service.
