I think that @nonescaping is a good default that goes along the same lines on why I use `let` over `var. </div><div>When I learned about @nonescaping I found myself using it more and more but it felt like having to use `const` in C++ and I thought why isn’t @noscape the default. </div><div>I think that is @nonescaping was available before swift 1 came out that the core team would have made it the default. </div><div><br class=""></div><div>How would somebody unsafely cast an escaping closure to a non escaping?
