template< typename T > boost::function<T(T)> foo( T n_ ) { //Works, but leaks n //T *n = new T( n_ );
//Doesn't work boost::shared_ptr<T> n( new T(n_) );
return ( *n += _1 );
I think that you need to wrap n in boost::lambda::constant:
return *constant(n) += _1;
Without it, *n is evaluated immediately.

Peter, Thanks for the reply. I must be doing something dumb, because now I'm getting a build error. I think this *might* be the important part: /usr/include/boost/detail/is_incrementable.hpp:59: error: no match for 'operator++' in '++boost::detail::is_incrementable_::impl<boost::shared_ptr<int> >::x' The 799B source file is here: http://mark.santaniello.net/files/hof2.cpp The 19KB error message is here: http://mark.santaniello.net/files/err.txt :) -Mark
