Even though I don't think it applies to scoped_ptr, I think it would be a 
nice little addition to boost/utility.hpp.

But the name ought to be a bit more explicit, so that readers will know by 
sight why it is used.  delete_complete_type() or something.

Hum...  Exactly when would you use it?  Presumably mostly in 
templates.  How does a template know if the delete requires a complete 
type?
