Hi Christian,

Personally I don't like having two ways of doing things. It makes it harder for people to read scripts. However, I think the proposed syntax is significantly more elegant than today's array() which makes me think twice about the idea and possibly making an exception to the rule. I think it'll improve the look of PHP scripts. Also I think people calling methods using call_user_method([$obj, "method"]); will find it sexier than the array() syntax. I guess I think it'd be interesting to see what other's think. Also, another point to check is if list() can also be converted into [] because having a hybrid wouldn't be too nice.

I propose to add an alternative (backward compatible) short array creation syntax: $a = [ 1, 2, 3 ]; and $a = [ 'a' => 42, 'b' => "foo" ];

It can also be used in function calls: img(['src' => "logo.gif", 'alt' => "Logo"]);

Reason behind this change: Arrays are used a lot and should therefore have as little syntactic overhead as possible. And I think the short syntax is also easier to read and write.

A patch for the parser is trivial and is attached for Zend2.

Note: I checked the newsgroup archive but couldn't find a discussion about this. After not hearing back about my proposed enhancement to debug_backtrace() and the dangling comma for function call parameters being rejected I wonder if I'm using the right mailing list for this :-)
