In any case the ctors are only used once each & probably might as well have them both explicit.
> Or maybe make only one ctor that takes the index explicitly and use it from begin/end - not sure there's much value added by having two ctors here, and honestly I'd have expected the no-arg version to start at zero, and the arg-taking version to start wherever you want, and I see they're the opposite, so that'd probably reinforce the idea that just having the one that takes an explicit index might be less confusing.
I copied all of this from somewhere else in LLDB without giving it much thought because honestly I'm not sure this iterator is that much better than then existing `LockingAdaptedIterable`. Sorry for making you review this half-baked code...
