That's the problem indeed. Traversable interface doesn't even offer  
methods for returning current key and PDOStatement doesn't count total  
number of rows at all.

I've changed SVN version of PHPTAL to be less picky about what it  
iterates and use keys obtained from foreach() instead of getting them  
via interfaces or array_keys(). This allows basic iteration of  
PDOStatement, DOMNodeList, etc.

I'll think about supporting it better (which might require  
introspection of template code to check if repeat/last, etc. are  
used), but for now, if you need all repeat properties, my suggestion  
is to use PDOStatement::fetchAll().
