[Boost-users] Lack of release() in scoped_ptr and scoped_array

I finally decided to switch to boost from my own implementation of some 
helper classes, and I noticed that scoped_ptr and scoped_array in boost lack 
the release method(). I had to fall back to std::auto_ptr.

However, this seems like such a basic and fundamental problem that I have 
started to fear that I am missing something obvious... The usage I got used 
to was something like this:

{
    scoped_ptr<A> temp( new A() );
    verify( temp.get() ); // might throw
    store_in_a_very_special_place( temp.get() ); // might throw; and I 
should keep ownership if thrown
    temp.release();
}

I though this was good practice to make code exception safe. Sure I could do 
it with try-catch but that gets messy if I allocate multiple instances etc.

So the question is:

1) is there something wrong with the concept of release()?
2) if release() is not evil, is there any other reason why is it not in 
boost::scoped_*?
