[swift-evolution] Better Swift interface for NSDecimal

Using NSDecimal from Swift isn’t fun. There are UnsafePointer<NSDecimal> all over the place.
It would be nice to have a Swift-like interface to work with NSDecimal. This can easily be achieved using an extension on NSDecimal. Here is something I quickly hacked together in a playground: https://gist.github.com/florianreinhart/99bb3a079075eaf640f1
The extension exposes all NSDecimal functions as mutating instance methods on NSDecimal. The instance methods throw if there is any error provided from the underlying NSDecimal function. I have also added operators, but I am not sure if this is a good idea.
What do you think about this?
How is the process of integrating something like this into Swift (since this is an API addition to Foundation)?
