[swift-evolution] [Proposal] Swift 2.2: #if swift language version

[Rod Brown]

While that is true, I suspect with the race to a stable language, the plan is to design features as if the language were to stay solid. I wonder about the wisdom in designing part of the language to handle the fact they are not finished designing the language.

Perhaps as an compromise, they could treat different versions of swift as features in and of themselves?
