/*
This includes all Objective-C runtime headers for convenience. It also creates wrappers around objc_msgSend() out of necessity.

cgo doesn't support calling variable argument list C functions, so objc_msgSend() cannot be called directly.

Furthermore, Objective-C selectors work by basically sending the arguments to objc_msgSend() verbatim across the wire. This basically means we're stuck making wrapper functions for every possible argument list. What fun!

The format should be self-explanatory.
