// Each input is parsed multiple times and the results are averaged. We
// do this for two reasons:
//
// 1. To warm up the interpreter (PEG.js-generated parsers will be
// most likely used repeatedly, so it makes sense to measure
// performance after warming up).
//
// 2. To minimize random errors.
