New Revision: 191453<br>
<br>

Log:<br>
Implement a rudimentary form of generic lambdas.<br>
<br>
Specifically, the following features are not included in this commit:<br>
- any sort of capturing within generic lambdas<br>
- generic lambdas within template functions and nested<br>
within other generic lambdas<br>
- conversion operator for captureless lambdas<br>
- ensuring all visitors are generic lambda aware<br>
(Although I have gotten some useful feedback on my patches of the above and will be incorporating that as I submit those patches for commit)<br></blockquote><div><br></div><div>[...]</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
