[boost] ptr_container: ptr_map_adapter interface

Hello,

I've been using ptr_map lately and have a few questions regarding its 
interface.

Below is a signature of `insert' function as declared in ptr_map_adapter:

std::pair<iterator,bool>  insert( key_type& k, value_type x );

Why is `k' a non-const reference?

To imply ownership transfer, couldn't `x' be of 
`std::auto_ptr<value_type>' type instead?

What happend to std::pair as an argument of insert? Was symmetry with 
std::map dropped for a reason here?

Cheers,
