Instead of providing a separate class for keeping the parser alive during its own call back, just delay a possible `.close()` call until the stack has cleared completely.

It's trivial, but can you make this a top level function instead of allocating the closure?

Does it make much of a difference if it’s not a closure? I would expect engines to optimize that away?

Yeah, it makes a difference. In this case it would likely be trivial but it definitely has an impact. The engines do not optimize away the closures at this point
