Description:
------------
I would like to suggest an extended foreach syntax like this:
<?php
foreach ($a, $b, $c as $k => $i)
  echo $i;
?>
Which would result in the same execution as current:
<?php
foreach (array ($a, $b, $c) as $x)
  foreach ($x as $k => $i);
    echo $i;
?>
The reason for requesting this is (simplicity and) possibility of lazy-evaluation of the source arrays. The source arrays can be expressions that take time to compute; or consume large memory each while they exist; and the body of the foreach can break the foreach cycle, rendering a lazy-evaluation quite worth the trouble. Example:
<?php
// several not-so-easy-to-compute arrays
foreach (
  $item1->GetChilds(),
  $item2->GetChilds(),
  $item3->GetParent()->GetChilds(),
  $item3->GetComputeSomethingDifficultChilds()
  as $child
)
   // searching for a child with a special name
   if ($child->GetName() == 'something') break;

// now we got a child of such name (or the last cycled child)
print_r ($child);
