[swift-evolution] Modernize Switch/Case Statements?

I would argue that if you are in need of multiple blocks within a function that your function is not focused or concise.  Unlike a language like Java, you can define functions within another function which greatly improves code structure as it allows you to write chunks of code that is used multiple times in a function but no-where else.  

Haravikk, curious — how big are these functions that you feel the need for multiple blocks?

Currently they just result in a “trailing closure separated by multiple new-lines” warning, so they could perhaps be made available, in which event you could use them in larger case statements whenever you wished.
