RE: [PHP-DEV] [RFC][List/Assoc\unique]

Hi Ilija, Thanks for the RFC. In general, I like the idea but there are certain things not clear to me. 1. What will happen if we pass a list to Assoc\unique? ``` Assoc\unique([1, 2, 3, 1]); ``` 2. What will happen if the array (no matter list or assoc) contains pure value and reference which are strict equal? As the RFC says "references are preserved." ``` $a = 1; $arr1 = [$a, &$a]; $arr2 = [&$a, $a]; List\unique($arr1); List\unique($arr2); ``` 3. Currently the RFC (proposal section, function signature) claims the parameter are bool type, which is obvious wrong. But this is just a minor mistake, what I really want to ask here is do we support array only or any array like input? > Side note: I *really* hope the discussion will be about more than just the namespaces. Adding two new namespaces with single function doesn't look good to me, especially I cannot think of anything that we may add to these two namespace in the future. Regards, CHU Zhaowei
