 From http://www.boost.org/doc/libs/1_36_0/libs/smart_ptr/scoped_ptr.htm:

"If scoped_ptr had a release() member, it would become possible to 
transfer ownership of the held pointer, weakening its role as a way of 
limiting resource lifetime to a given context. Use std::auto_ptr where 
transfer of ownership is required. (supplied by Dave Abrahams)"

But there already is a way to escape the scope, via swap().

Would it make more sense to just provide release() and have users 
specify const if they want?  (const scoped_ptr/scoped_array would 
effectively disallow swapping/releasing.)
