These are drop-in replacements of the respective STL +algorithms that can be a few times faster when applied on immutable +sequences. + +For further convenience they can be passed in just a container where +the standard library algorithms require being passed in two iterators. + +.. note:: + + They are a similar idea to `structure-aware iterators`_ + but implemented using higher order functions in order to support + structures of any depth.
