Chapel, the Cascade High Productivity Language, is a parallel programming language developed by Cray. It is being developed as part of the Cray Cascade project, a participant in DARPA's High Productivity Computing Systems (HPCS) program, which had the goal of increasing supercomputer productivity by the year 2010. It is being developed as an open source project, under version 2 of the Apache license.. Read more on Wikipedia...

Example from hello-world:
writeln("Hello World");
Example from Linguist:
writeln("Hello, world!"); // print 'Hello, world!' to the console
