Details

We should have a Debugger hook for when a debuggee coerces a value to NaN.
What's the rationale? (vs other kinds of coercions, which could all be pretty surprising?)

It's SUPER annoying, difficult to track down the origin, and the false positive rate is near 0%.

If you have other cases that have those same properties, we should generalize the hook to include those cases as well.
