> The key placed in the ScanYieldException is not the start of the initial
range. It is the key where it left off in the underlying scan
You can't guarantee this. What I am saying is: what _if_ the key you see is
the same?
Your last comment makes me think that you intend for this exception to
never be thrown when "no progress" was made. If that's correct, documentation
needs to adequately warn..
