[swift-evolution] [Proposal] Remove behavior on AnyObject that allows any obj-c method to be called on it

> Since the dynamic keyword defines a function that goes through runtime dispatch, the same very runtime dispatch that current AnyObject calls go through, it would make sense for the new stuff to be called something like dynamic or dynamic_binding or DynamicObject or whatever.

Or add a "here there be dragons" keyword on the expression, like the `try` keyword. Straw syntax:

	let foo = Foo()
	yolo foo.someWeirdMethod()
