There is a really nice example of the "goto" semantic for proper tail calls in "Programming in Lua". The example is a maze or adventure game where you need to move into different rooms (north, south, east west). http://www.lua.org/pil/6.3.html http://www.lua.org/pil/6.3.html It's a nice example because it's simple, it doesn't confuse/intermix the concept with recursion, and it's an effective solution because it allows you to achieve the goal of moving to rooms (i.e. s state machine) elegantly. And in a language without proper tail recursion, it is easy to envision how you could accidentally blow up the call stack.
