Subject: RFC: alternative callback syntax
From: steve@mrclay.org (Steve Clay)

Hello,

https://wiki.php.net/rfc/alternative_callback_syntax is a proposal for a simple 
alternative syntax for creating function callbacks.

The basics: Given a function/method call, replace the argument list with "::function". PHP 
would evaluate this as a callback for the function/method, fully resolving any 
class/function names according to the current namespace and any use statements.

In my opinion this syntax would aid readability and benefit users via fewer typos and 
namespace errors, and via (hopefully) better IDE support.


I welcome any feedback. I don't have adequate C skills to offer a patch at the moment, but 
I generally read everything I can get my hands on about how PHP features are implemented 
and am not afraid to jump in.

Thanks for your time.

P.S. I've kicked around this idea around for awhile, but Ralph Schindler's idea for using 
::keyword provided a better path to BC, and more attractive/meaningful syntax.

P.P.S. I'm unaware if it's customary to throttle the release of RFCs, so I apologize for 
hogging any attention away from those under discussion.

Steve Clay
