just because latter is a "method". And that, by you, is 
hunky-dory? Whether it's a method or a free function, it's 
written to work on *shared* data. Of course it wouldn't be safe 
if you allow any non-shared data to become shared without the 
programmer having a say in this.

Out of curiosity, when it comes to primitives, what could you do 
under MP in void "atomicInc(shared int*)" that would be 
problematic?

void atomicInc(shared int*) {
  // i.e. what goes here?
}
