I noticed that the current parsing of the {foreach} function casts the from parameter to an array so that it's impossible to use php5's iterators on objects.

A quick and perhaps dirty workaround for this is to change Smarty_Compiler.class.php:1168
from:
[php:1:bad303cb1b]$output .= "if (count(\$_from = (array)$from)):\n";[/php:1:bad303cb1b]
to [php:1:bad303cb1b]$output .= "if (is_object(\$_from = $from) || count(\$_from = (array)$from)):\n";[/php:1:bad303cb1b]

that will fix it only if you don't use the name= attribute as it needs the total count of items determined by count(), but I think you won't need that in connection with iterators...

would be nice if you could take care of this in the next release...
