We've been daydreaming about the ability to do something like this

PHP: $data = array("zoo", "orange", "car", "lemon", "apple"); usort($data, function($a, $b) { return strcmp($a, $b); }); var_dump($data); # data is sorted alphabetically

I'd LOVE it if there was SOME difference between this and a normal 'function' definition... I guess we're kind of stuck with 'create_function' being the mess that it is. But perhaps something like 'temp_function' or 'local_function' or 'lexical_closure' or something similar. Even 'horse' [*] would be fine by me. I think it muddies things too much to have it just be 'function' with no name after it. +1

A function with a name is no longer anonymous ;)

I am not suggesting that there be a name. I am suggesting that the reserved keyword for an anonymous function should not be 'function', the same as a normal function.

I don't have anything against 'function', I think JS uses the same syntax - function without a name. If you change it to something different, e.g 'callback', then you loose the information that it is actually a function $error_func = callback($msg) { file_put_contents('php://stderr',"Error: $msg\n"); } vs. $error_func = function($msg) { file_put_contents('php://stderr',"Error: $msg\n"); } The second one looks better for me.
