I think it's a useful addition, but it does cause a little overhead (though

Actually event emitters already call in the scope of the emitter, so there
is no need for a specific this value there. Just subclass EventEmitter

Mainly the overhead. Bind creates a new function
If I'm not mistaken, bind() has the same technical drawbacks as using an
anonymous function (higher memory usage, more garbage collection, and
slower says Tim), but it does solve the maintainability / prettiness issue.
I just want to point out that Raspberry Pi is now shipping.
NodeJS is a very

Though significantly faster than making a closure, .bind is still fairly
expensive, and creates a heap allocation, which adds to heap pressure and
time spent garbage collecting, which (in our, admittedly, not particularly
normal, case) is our biggest performance concern - with a real-time system
