Swift - What's Your Role in the Development of Swift?

i think swift is the first language to really take value sementic seriously, and that was mostly because i fought for it. There's like a different world of trade offce around value semitics that i now see, that wasn't visible to me as a cplus plus programmer going into the project. You know, i'm a little ignorant on swift. Ntresting. Can you give me anything more? Li o, wait until you start.
