I always appreciate when libraries and tools are carefully engineered for performance, provided the abstraction holds and the thing solves the problem it is supposed to. It seems to make sense to invest the most energy in optimizing and otherwise improving the tools that are more general and used widely. In which case this library clearly fits the bill. On the other hand in application code, possibly while still experimenting or developing ideas it makes most sense to aim for maximum readability and simplicity. Optimization can be left for when there is a proven need for it.
