if I attach the above code to a click handler, then when the bug occurs, it occurs on
every click until I manually scroll the page, then it starts working.

// This is called whenever any data changes that affects the weekly totals
// What we do in that case is modify our local representation of the weekly data and emit an event
// This way, modules can listen for that event and respond to it without having to wait for

// It would be very simple to write this function to sort-of mimic let;

lett({
    'blockScopeVar': 4
}, function (blockScopeVar) {
    //blockScopeVar === 4 // true
});

// Then when you want to change the code to actually use let, it's fairly easy;
// just write your let declarations and rip out the callback's innards;
