Good morning,

Perhaps a future version of PHP (PHP 6? 5.7?) could have lexical scoping with a
"let" keyword? At the very least, it would make foreach() with a reference less
of a problem:

    foreach ($array as let &$a) {
        $a = 3;
    }
    // $a is not in this scope - no need to worry about accidentally changing
last array item

Any thoughts?
