Ive modified the ptr_map_adapter in the operator
const_reference operator( const key_type& key ) const
//return lookup( key );
iterator i = find( key );
if( i != end() )
i = const_cast<ptr_map_adapter_base*>(this)
and the non-const just dont have the const_cast, but this way I think
value_type is default-constructed and then copy-constructed isnt? well,
this isnt very efficient, but to my needs it is already better.
