Seems that this /could/ create issues if you did something like this:
var timers = {};
var timer = setTimeout(function() { ... }, 100);
timers[timer] = timer;
for (var ii in timers) {
clearTimeout(ii);
unset(timers[ii]);
}
The spec does specify that it must be a number, however this was likely a
calculated deviation because the possible performance benefits of using a
non-scalar seem pretty clear.
