 I've found myself wanting this on a couple of occasions with 1.33.1, and
 I've done it with boost::shared_ptr:

 {{{
 #!c++
 boost::shared_ptr<fs::path> removeFile(&file, bind(&fs::remove,
 boost::cref(file)));
 }}}

 That didn't work with 1.34.1 (maybe due to compiler intricacies), so I did
 it properly:

 {{{
 #!cpp
 class scoped_file {
 public:
     explicit scoped_file(const std::string& file) : m_path(file,
 boost::filesystem::native) {}
     explicit scoped_file(const boost::filesystem::path& file) :
 m_path(file) {}

     ~scoped_file() { boost::filesystem::remove(m_path); }

 private:
     boost::filesystem::path m_path;
 };
 }}}

 That might be something to add?
