I like that the closure parameters are inside the closure, to me it makes as 
much sense as outside. They're the input, so as much in as out.

I have nothing against `in`, but I wouldn't be against a sensible replacement.
I like `=>`, but I'm concerned it might be confused with `->` by beginners in 
swift.
