I think that I may have written it, or been involved with writing it. It 
would have been written to cover the original design, as Dave says.

The intent was probably to indicate what the smart point implementation 
itself might throw. If they don't already do so, the docs should also 
discuss exceptions which could be thrown by operations on the templated 
type.
