The idea is that users can write their own frame recognizers in Python (though I have not exposed this in this patch). I'll see if I can ad this!

Then again, I guess with the recognizers we're talking about here with C++ it will not be common, and so the one backtrace during your session where there's std::function stuff on the stack and it's omitted, it wouldn't be noisy. I don't know how frequent you think these recognizers might match for Swift code.

Thinking of it, it is probably good enough to explain this in `help thread backtrace` and `help bt`?
