Comment (by akio):

 Thank you very much for implementing this!

 Replying to [comment:13 nomeata]:
 > Voila, akio. Hack away! And let me know if `oneShot` makes a difference
 for your use case, I’d like to report on it in my thesis, which marginally
 mentions `oneShot` as well.

 In one of my benchmarks (serializing JSON), `oneShot` improves performance
 by 50%.
