 Imagine instead of climbing a huge staircase (deepening the call stack), you're bouncing on a trampoline. You always return to the trampoline's surface (a central control loop) before taking the next bounce (the next computation step)

 The Trampoline pattern is designed to execute deeply recursive (especially tail-recursive) computations without blowing the stack. It does this by replacing direct recursive calls with returning an object representing the next computation step. A controlling loop then executes these steps iteratively.
