Comment (by anonymous):

 That does not seem to be the case. The following fails for me:

 {{{
 #include "boost/spirit/home/support/utree.hpp"
 #include <cassert>
 int main()
 {
         boost::spirit::utree ut;
         ut.push_back(1);
         assert( ut.insert( ut.end(), 1 ) != ut.begin() );
 }
 }}}

 If one takes a look at boost::utree::end() it creates an iterator with 0
 as node ( makes sense I presume ). The guard is then:
 {{{
 if (!pos.node)
 {
         l.push_back(val);
         return utree::iterator(l.first, 0); // begin();
 }
 }}}
 As pos.node == 0 for all end() it would seem it doesn't matter how many
 items are in the utree. Perhaps I'm missing something?
