[swift-evolution] [Proposal] Remove force unwrapping in function signature.

[Saagar Jha]

I have updated the proposal here <https://gist.github.com/saagarjha/f33fecd4576f40133b6469da942ef453>. Since this is a potentially a source breaking change, I’d like this to be considered for Swift 3; unless anyone has any issues with it, I’m going to push this to swift-evolution.
