-------------------------------------------------+--------------------------
 boost::mem_fn only supports calling member functions through proxies when
 the proxy type has a matching get_pointer function. This is not necessary
 for std::mem_fn (20.8.10) as the second or fourth item of INVOKE (20.8.2)
 should apply in such a case.

 A solution would be to change _mfi::dm::call(U const& u, void const*) to
 simply call (*u).*f_

 I couldn't find any documentation why exactly get_pointer is used and
 don't know which implications this might have, but it would be a nice to
 have feature (and would also allow mem_fn to work on iterators which are
 often used as handles).
