Misc side notes: * There is no expected behavior for negative a negative weight. Arguably, the only reasonable interpretation is what it already does (reduce the cumulative total). * Running simulations is a primary use case for choices(). Generally, running time there is important. * During the design phase, none of the other implementations studied had incorporated a scan of the inputs for negative weights. * bisect() does not check to make sure its inputs are sorted. The results for unsorted data are undefined. It is a documented precondition.
