• Partial events and constructors
• Collection expression arguments
• Extensions disambiguation syntax

On the partial constructors, there seems to be no possibility to split constructor into several parts, so that different generators would be able to initialize (readonly) fields fields created by them. A feature like this wouldn't be that critical for usual methods, but constructors are special because readonly fields cannot be initialized in helper methods.
