Hm..yeah...I guess you can use

map.at( "foo" );

if you want the exception to be thrown. I think you're right
it should call insert a heap-allocated object.

I will change this for the post-review. In the meantime, you can make
a new function in ptr_map_adapter using lookup()
as a template to get the behavior you need.

I'm glad to hear that.
