[Boost-users] shared_from_this from constructor

Is there a way to call shared_from_this() from a constructor?

It seems like a bad idea.  Since the object is still being created, it 
would be difficult for anything to have a shared_ptr to it.  And that 
violates a documented precondition of shared_from_this(): "There must 
exist at least one shared_ptr instance p that owns  t."

If it's not possible or just a bad idea, how about a note in the 
documentation at:
    http://www.boost.org/libs/smart_ptr/enable_shared_from_this.html
to say something like: "Calling shared_from_this from a constructor will 
not work, since there is no shared_pointer which owns the object."?
