good practice in c++ (lazy evaluation) http://stackoverflow.com/questions/4613551/good-practice-in-c-lazy-evaluation work or it is bad idea if Yes why Thanks in advance if currentNode 0 currentNode element return c lazy evaluation share improve.. is bad idea if Yes why Thanks in advance if currentNode 0 currentNode element return c lazy evaluation share improve this question.. no further subexpressions are evaluated.
