Comment:

 Fixed in trunk (70832). Will be merged in 1.47.
 Following is now possible:


 {{{
 void test(const player& p)
 {
    const player_::Stopped& s1 = p.get_state<const player_::Stopped&>();
    s1.cfoo(); //const
    player_::Stopped& s2 = p.get_state<player_::Stopped&>();
    s2.foo(); // not const

    const player_::Stopped* sp1 = p.get_state<const player_::Stopped*>();
    sp1->cfoo(); //const
    player_::Stopped* sp2 = p.get_state<player_::Stopped*>();
    sp2->foo(); // not const
 }
 }}}
