// Tests the creation of items with a non-recursive function binding
// Note: Through an unfortunate oversight, this benchmark is mildly broken.
// The loop never updates the 'x' value. However, this benchmark has already
// given some insights, and changing it (as any other benchmark) would
// invalidate past data causing confusion, so it has not been altered.
//
// See sum10k_fixed for a working version.
