Hello! In <http://people.mozilla.org/~jorendorff/es6-draft.html#sec-execution-contexts>, a paragraph reads:
| Transition of the running execution context status among execution | contexts usually occurs in stack-like last-in/first-out manner. | However, some ECMAScript features require non-LIFO transitions of the | running execution context. I wonder what this means? My first guess was that this refers to generators, whose contexts enter and leave the stack multiple times at will (in contrast to a normal context that enters only once and is destroyed after being suspended), but I found that generator contexts are pushed to and popped from the stack as everything else. On closer inspection, I found that the spec sometimes uses the term "remove" and sometimes "pop" when suspending an execution context, but I can't imagine a case where this did not refer to the topmost context on the stack. Can you give me an example? Did I miss something?
