Let me start by saying I realize how entirely dangerous this is. Currently there's no good ergonomic way to do this, and in order to implement the backbone of the Stream classes, we need something that resembles an emitter.

Current Limitations:

1. Callback signatures must match runtime assertions
2. EventEmitter is treated as abstract
3. Callback parameters up to length 10
4. callback must return void
5. Emit still too large. Requires switch statement to determine callback argument length
6. emit function doesn't match @types/node type arguments. It still requires explicit types

emitter.emit<A, B, C, D>(a: A, b: B, c: C, d: D); // etc.
