Of course, that makes sense. The top-most type will always be the same as the return type. (Bangs head on desk !).<br /><br />Looking through the implicit cast does then allow me to check for 'undesirable' type conversions.<br /><br />Thanks, I knew it would be easy ;-)<div> </div>Phil.<br /><br> <div style="font-family: Courier New, courier, monaco, monospace, sans-serif; font-size: 12pt;"> <div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"> <div dir="ltr" > <font size="2" face="Arial"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> John McCall <rjmccall@apple.com><br> <b><span style="font-weight: bold;">To:</span></b> Phil King <phil_king@rocketmail.com> <br><b><span style="font-weight: bold;">Cc:</span></b> Clang dev mailing list <cfe-dev@cs.uiuc.edu> <br> <b><span style="font-weight: bold;">Sent:</span></b> Friday, 23 March 2012, 18:09<br> <b><span
