Hey, the reason for the long times on the playground is actually that we’re having to wait for build servers to boot up and then build the code before we can finally ship it off to our backend for analysis. We’ve had quite a bit of feedback on this slowness and we hope to eliminate some of this constant factor boot up and compile time soon, and for what remains make it clear that this is what’s happening in the status box.

So although it might seem like it, we’re not actually doing any looping, we’re doing constraint solving as you’ve mentioned.
