const function variable cannot reference itself

[jamiewinder]

TypeScript Version: 2.0.2

With this code:

const mouseUpListener = (upEvent: MouseEvent) => {
    // (do something)
    window.removeEventListener('mouseup', mouseUpListener); // *1
};

I get an error on line *1 saying: "Variable 'mouseUpListener' is used before being defined". I can change const to let and it works, but I'm not sure I see the difference (the function body won't ever run until the variable is set, so is const).

Is this expected / correct?
