[swift-evolution] [swift-evolution-announce] [Review #2] SE-0091: Improving operator requirements in protocols

A few questions:

1. What is universal lookup? How is this different than the compiler having to search a crowded namespace? I'm really trying to understand how this is making it easier for the type checker. 

2. If operators are a special case, why not replace static/class func with an "operator" keyword? Requiring static/class seems like an implementation detail to get this universal lookup. 

3. Will the static vs class distinction ever be fixed or cleaned up? Isn't there a way to share one keyword for this same feature across all types?

Regardless, I'm still giving this a +1. 

I'm just hoping we can:
- reduce some cognitive burden
- add a little character
