SE-0289 (review #2): Result Builders

[Douglas_Gregor]

There exists a mental model where @ViewBuilder decorates the type instead of the parameter. It is wrong, granted. But it takes time to understand how and why it is wrong. There lies the opportunity for mistakes, and a good reason for a fixit.

Sure, the diagnostic could be better. Please file a bug at bugs.swift.org and we'll get to it.
