in thread RFC: Implicit Parallelization Pragma

Win32 already has this ability, they call them fibers.

Fibers will not help with parallelization. They are essentially a fancy incarnation of C's setjmp/longjmp functions. An application can change its execution context with fibers, but it cannot schedule fibers in parallel on multiple CPUs.
