Still not working:
<?
function loop(Traversable $traversable)
{
foreach($traversable as $k => $v)
echo "$k => $v\n";
}
$primos = explode(" ", "1 2 3 5 7 11 13 17 19");
// loop($primos); // does not work
loop(new ArrayIterator($primos)); // works
?>

Please try 5.3.2 or 5.2.13.

It should also expose interfaces ArrayAccess and Countable. It's very
frustrating when you use type hinting to force iterable structures or
array-like accessible and it comes out that you can't pass array
themselves.

Description:
------------
Traversable is an internal interface that says "I can be used in a
foreach". Since array can be used too, would be nice if array be
accepted internally in parameters that expect traversable.
Reproduce code:
---------------
<?
function acceptArray(array $t) {
echo "\n".__FUNCTION__."\n";
foreach($t as $k=>$v) {
echo "$k=>$v\n";
}
}
function acceptTraversable(Traversable $t) {
echo "\n".__FUNCTION__."\n";
foreach($t as $k=>$v) {
echo "$k=>$v\n";
}
}
$test = array("is", "array", "traversable", "too", "?");
acceptArray($test); // ok
acceptTraversable(new ArrayIterator($test)); // ok
acceptTraversable($test); // would be nice
?>
Expected result:
----------------
acceptTraversable($test); shoud accept an array, since it's too a
Traversable structure(can be used in a foreach).
Actual result:
--------------
Fatal error: Argument 1 must be an object of class Traversable
