You have got presently witnessed a range in use (for strings), it can be expressed as very low .. high and may be The most beneficial ways of expressing interfaces and parameter values, such as:
(Very simple) An assignment operator should really return T& to help chaining, not possibilities like const T& which interfere with composability and putting objects in containers.
