?? it's a formal language and concepts are abstract so the language specific parts transcend the implementation. in other words i can show you a selection sort with pebbles and it's easier to grasp, than showing you the implementation in pseudo-code.
Understanding the concept is more important than repeating/copying a sentence which often is done (stackoverflow)
The question to me already is one useless poll, because pythagoras explained his math and algorithms with pebbles so if people did 2500 years ago, so obviously it does work.
