https://svn.lrde.epita.fr/svn/oln/trunk/milena Th�o, si tu veux faire la r�vision 2000, c'est le moment ! ;-) Index: ChangeLog from Roland Levillain &lt;roland(a)lrde.epita.fr&gt; Have mln:p_set be able to erase its elements. * mln/core/p_set.hh (mln::p_set<P>::remove): Enable this method. * mln/core/internal/set_of.hh (mln::internal::set_of_<E>::s_): Make it protected.
