E.g., { function lazy_inner(b = somevar) { let somevar; } } If we don't produce the same scopes, PreParser thinks that the unresolved variable inside the default parameter resolves into the variable declared inside the function. Thus, it's not correctly recorded as a free variable. One part is already done by https://codereview.chromium.org/2638333002 . But at the laziness boundary, we still produced different scopes. Unlike previously thought, this is also needed for lazy inner function correctness, not only for "preparser scope analysis" (ie., skipping inner functions).
