Subject: Re: [PHP-DEV] Proposal for a new array function

My personal take on this:

Let's add just more 1 function over a 99999 function's array API, because I
want to optimize 3 lines in my PHP code, and language lack of Generics
while we still refuse to carefully think about a proper OO Collection API.

Regards,
