RFC proposal - unpack iterator

Hello, From PHP 5.6 we have possibility to add variadic functions and unpacking arrays via *...* Would be nice to extend responsibility of *...*. Sometimes in code I can find lines similar to the following: $result = array_merge(['some value'], ['some other value'], $array); I would like to shorten this line to the following: $result = ['some value', ['some other value'], ...$array]; And even allow to unpack more than one array: $result = ['some value', ['some other value'], ...$array, ...$secondArray]; Using new operator we can produce shorter and more clearable code. I would like to create RFC for my proposal. If you think idea can be useful, please give me an access for creating RFC. Best regards
