PHP "list" function interface change for PHP 7.0

I was going through some PHP function definitions and came across the following warning for the list function:

[B]Warning[/B]:  In PHP 5, list() assigns the values starting with the right-most parameter. In PHP 7, list() starts with the left-most parameter.

Is that going to cause issues in the Zen Cart base code?

Re: PHP "list" function interface change for PHP 7.0

In all the testing I've done I've not run into any issues with this.

I think it's because the ZC code doesn't do [] notation in its use of the list function, such as:```
list($a[], $a[], $a[]) = [1, 2, 3]; // this gives different results in PHP5 vs PHP7

Thanks, DrByte. I (obviously) didn't read the fine print on that warning!

Haha. At least you made me spend a half hour to investigate and run a bunch of code samples thru multiple versions! I think I'm satisfied that there's no incompatibility in this case.
