The idea for closure labels is that the labels would still be part of the name, but that you could give compound names to closure variables in addition to named functions. That would let you write something like:</div><div class=""><br class=""></div><blockquote style="margin: 0 0 0 40px; border: none; padding: 0px;" class=""><div class="">let foo(bar:) : (Int) -> String = { "\($0)" }</div><div class="">foo(bar: 0)</div></blockquote><div class=""><br class=""></div><div class="">Or, with a bit more sugar:</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>let foo : (bar: Int) -> String = { "\($0)" } // Notationally, we write the labels with the type, but they become part of the 'let' name</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>foo(bar: 0)</div><div class=""><br class=""></div><div class="">-Joe</div></body></html>
