[Boost-users] mpl::switch_

Is it me or is mpl::swich_ both undocumented and non-working ? I managed to get this : template struct switch_ {   typedef typename find_if,T> >::type iter_;   typedef typename deref::type pair_;   typedef typename second::type f_;   typedef typename apply1< f_, T>::type type; }; working properly. Seems the current swich_ use lambda<> where it shouldn't. Is this a known bug or is there something bound to replace switch_ in the near future ? SHould I fill a trac ticket about this ?
