I'd like to propose an additional test to ensure closures can all themselves:
<?php
$i = 3;
$lambda = function ($lambda) use ($i) {
if ($i==0) return;
echo $i--."\n";
$lambda($lambda);
};
$lambda($lambda);
echo "$i\n";
?>
Expected output:
3
2
1
3
I see exactly one problem with the patch, which is that the above script
shouldn't work without "use (&$i)".
I find it counterintuitive that the creation of the lambda creates a copy of
$i, but all invocations of $lambda use a reference to the same $i.
For n calls to $lambda, there are only 2 copies of $i (one global, one static
in $lambda) where I would expect n+1 copies.
