[swift-evolution] [Pitch] Make `return` optional in computed properties for a single case

[Adrian Zubarev]

I'll write a small proposal tomorrow for that behavior (not only for computed properties of course)! Today I'm too busy.  

Thank you for your positive feedback.

As I understand it, one of the reasons ++/-- were removed was due to the increased "burden to learn Swift as a first programming language.” This is the sort of thing that becomes another one of those special cases that has to be explained to someone new to Swift.
