[boost] [ptr_container] indirect_fun - do we still need it?

Thorsten, Now, when we got rid of ptr_iterators, we don't need indirect_fun, do we? At least as part of ptr_container library? P.S. About copyability: may be then provide some cloning mechanism like: ptr_vector<int> a; ptr_vector<int> b(a.clone()); b = a.clone(); Where ptr_vector<T>::clone doesn't create clone immeadiately, but returns some object that refers to this, and ptr_vector<T> has ctor and assignment operator taking that object. Thoughts? -- Pavel Chikulaev
