Hello,
<div class=""><br class="">
</div>
<div class="">I have a language syntax proposal. I've read the Swift evolution guidelines and hopefully this is the proper way to start. So, my proposal is:</div>
<div class=""><br class="">
</div>
<div class="">Permit a shorthand syntax for invoking the supertype implementation of a property or function. A single statement 'super' is equivalent to invoking the supertype implementation, forwarding the arguments unchanged, and returning the result. For
example, the following samples:</div>
<div class=""><br class="">
</div>
<div class="">
<div style="margin: 0px; font-size: 11px; line-height: normal; font-family: Menlo;" class="">
<span style="color: rgb(187, 44, 162);" class="">override</span> <span style="color: rgb(187, 44, 162);" class="">func</span> mouseEntered(theEvent: <span style="color: rgb(112, 61, 170);" class="">NSEvent</span>) {</div>
<div style="margin: 0px; font-size: 11px; line-height: normal; font-family: Menlo;" class="">
<span style="color: rgb(187, 44, 162);" class="">super</span></div>
<div style="margin: 0px; font-size: 11px; line-height: normal; font-family: Menlo;" class="">

<div class="">Alternatives/complementary ideas:</div>
<div class=""><br class="">
</div>
<div class="">- Require `<span style="color: rgb(187, 44, 162); font-family: Menlo; font-size: 11px;" class="">super</span><span style="font-family: Menlo; font-size: 11px;" class="">()</span>` or `<span style="color: rgb(187, 44, 162); font-family: Menlo; font-size: 11px;" class="">super</span><span style="font-family: Menlo; font-size: 11px;" class="">(...)</span>`
syntax for invocations which are function calls, for consistency with other function calls in the language and/or to indicate that arguments are forwarded</div>
