* an object can only be constructed from a handle<>. Other
interfaces are not for public consumption and thus not
documented. Use at your own peril.
I.e., it should be the first.
Actually, you should follow a logical extension of Peter Dimov's
guideline
(http://www.boost.org/doc/libs/1_36_0/libs/smart_ptr/shared_ptr.htm#BestPractices)
and give the handle<> object a name rather than making it a temporary.

Sure thing.
