Are you referring to some older version of any_iterator? The recent 
version I got from SF does not in fact contain adobe::any_iterator (the 
docs were not updated, it seems), but rather adobe::iter and 
adobe::bidirectional_iter - but I was not able to use these with B.MI so 
far.

 From the changelog it seems they changed the internals to use "the 
poly<> concept", whatever this means, and I guess this is when 
any_iterator disappeared...

Thanks,
Filip
