I like this case for OpenCilk's approach and wonder if any of the argument details are dated?

A parallel programming model with serial semantics maintains four real advantages over program models without serial semantics.

• The equivalent serial C++ program can easily be debugged and analyzed using existing development tools.
• The serial semantics of Cilk++ programs allows Cilk Arts to build better tools that analyze the performance and correctness of Cilk++ programs, and these tools offer strong guarantees about the program.
• The serial semantics of Cilk++ provides a real advantage to program testing and quality assurance.
• Serial semantics provides high performance while allowing you to design your program without specifying the number of processors on which the program will execute.
