Hi all,

I had a thought this morning and would like some feedback.  Don't you think
it would make sense to allow the callback psuedo-type to also allow the new
Closure class to be an acceptable data type?  A simple example that would be
nice to have working would be

<?php
$fClosure = function($val, $key) {
    echo "$key => $val" . PHP_EOL;
}

$aNumbers = array(5, 4, 3, 2, 1);

array_walk($aNumbers, $fClosure);
?>

Thoughts ?

I bet you thought you had something there... Ha!

It is a pity that the error is tagged as being on line 6 and not line 4.

I can see why. It isn't an error until the first non ; following the
closing brace (excluding comments).

So ...

$fn = function()
// comment
;

is valid.

Having the error on the same line as the closing brace would be nice though.
