I would really hate to explain to someone when <b class="">if</b> needs a <b class="">then</b> and when it doesn't.

Even right now, <b class="">if </b>syntax vs expression syntax is ambiguous:</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span><b class="">if let</b> foo = foos.filter { $0.isBar } {</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span> ...</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>}</div><div class=""><br class=""></div><div class="">3. If we can somehow solve all of this, I think I'll be +1 for replacing (A ?

Generally, I wonder how hard would it be for all statements to be usable as expressions?
