Not at all, so long as I use explicit temopries when calling new as
the docs say.

I've found I also have to change "iter->grow();" to
"(*iter)->grow();", but I think i've found a mechanism to solve this. 
I create a wrapper around the iterator whose operator* and operator->
returns a value_type& (i.e., *iter).  The modified code is attached,
any suggestions?
