// Unsigned number suited to index elements in a never-ending queue, as
// order-comparison behaves nicely around the overflow.
//
// Additive operators work the same as for the underlying value type, but
// expect "small" jumps, as should normally happen when manipulating indices.
//
// Comparison functions are different, they keep the ordering based on the
// distance between numbers, modulo the value type range:
// If the distance is less than half the range of the value type, the usual
// ordering stays.
// 0 < 1, 2^23 < 2^24
// However if the distance is more than half the range, we assume that we are
// continuing along the queue, and therefore consider the smaller number to
// actually be greater!
// uint(-1) < 0.
//
// The expected usage is to always work on nearby rolling numbers: slowly
// incrementing/decrementing them, and translating&comparing them within a
// small window.
// To enforce this usage during development, debug-build assertions catch API
// calls involving distances of more than a *quarter* of the type range.
// In non-debug builds, all APIs will still work as consistently as possible
// without crashing, but performing operations on "distant" nunbers could lead
// to unexpected results.
