<div dir="ltr">I have been working for a couple weeks (since the previous [newtype discussion](<a href="https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20151207/001821.html" target="_blank">https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20151207/001821.html</a>) ) on a related pitch. There seem to me to be multiple ways to solve this problem - a newtype(esque) keyword, struct subtyping, or forwarding as Matthew is suggesting. I’d hoped to have a discussion starter out before the holidays, but it takes a fair amount of work to put together even a decent draft for a proposal. This is top of my list currently for a way to contribute though. Looking forward to the ensuing discussions.<div><br></div><div>Thanks for the pointer on class delegation.

</span>Details are still brewing. I am not familiar with class delegation in Kotlin but will look it up. Thanks for mentioning it!<br>

I plan to spend a lot of time on Swift proposal work over the next week and a half but can't make any promises on timing. I made that mistake with my proposal on flexible memberwise initialization which ended up taking a couple weeks longer than I expected (for several reasons). What I can say is that this is pretty high on my Swift proposal priority list.<br>
