<div dir="ltr">Is having fixed arrays with large numbers of elements (256, 1024, etc.) going to cause issues with protocol conformance of tuples? I believe that since the type system doesn't currently have type-level integers, tuple protocol conformance is done via a hard-coded limit.</div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jan 29, 2016 at 1:30 PM, Austin Zheng via swift-evolution <span dir="ltr"><<a href="mailto:swift-evolution@swift.org" target="_blank">swift-evolution@swift.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">That makes sense, thanks.

Daydreaming aside, I think this is a great proposal and it'll make 256-member C array tuples less awful to work with.<br>
