So maybe we are talking about a bit different things... There are many ways to mess things with quick tests, so I won't push this topic more :-)

Indeed, automatic parallelization is a strong argument for VMs right now, since it doesn't require code modification. At the conference, Walter mentioned that D might be getting automatic parallelization of pure functions, though. I'm just afraid this won't apply to member functions, and since my programming style is so OO, it won't help me.
