[boost] iterators::function_output_iterator is missing in boost_1_32_0

Hello boosters! I've just found that function_output_iterator, mentioned in boost_1_32_0/libs/iterator/doc/function_output_iterator.html is missing in the boost or boost/iterator directories both in my own copy and in sf.net CVS. Neither me nor my compiler could found it. Was it deprecated? or removed accidentally? Best, Oleg Abrosimov
