Hello , I've found that ptr_unordered_map.insert has following signature (from code and latest doc)

std::pair insert( key_type& k, T* x );

that forbids calls like ptr_unordered_map.insert( myobj->id(), myobj) ,I wonder if this is by design , or some other reason ? why other overload takes const key_type& k as key type? and insert always call insert_impl which have const reference as key type ? any help would be appreciated.

It is by design.
