boost::none will be helpful as well: f(p1, p2, boost::none, p4);

Beside the headers, Google doesn't yield documentation on boost::none.

Could someone please explain it's intended use? I see none_t is a typedef to a member of none_helper, a struct with no members, and none is a const none_t, but I'd expect such a pointer to not be convertible to anything, so I'm not following on passing boost::none to a boost::optional as above, nor can't figure out the use for none. Can someone please provide some details / background info on none? Thanks
