WebApr 30, 2012 · The key feature of this implementation is that the recursive function times_two_recursive_impl uses a tail call to do the recursion: the value of calling itself is immediately returned, without reference to anything else in the function, even temporary variables. So, let's see what happens when we compile and run this: http://duoduokou.com/scala/17128993365083130855.html
