<p style="margin:0px 0px 1.2em!important">Question #1: Methods are still curried. If I’m not mistaken, there was an accepted proposal that uncurries methods. Is it going to be implemented for Swift 4 Stage 1?</p>
<p style="margin:0px 0px 1.2em!important">Question #2: Why nested tuple in type of <code style="font-size:0.85em;font-family:Consolas,Inconsolata,Courier,monospace;margin:0px 0.15em;padding:0px 0.3em;white-space:pre-wrap;border:1px solid rgb(234,234,234);background-color:rgb(248,248,248);border-radius:3px;display:inline">print</code>? Is it just a formatter bug, or… do functions still take tuples under the hood? If so, then perhaps, implementation needs to be modified to actually use new model, and not just make it look like it does.</p>
