Converting to bool can be problematic, as throughly explained at

The optimum way to do this is to convert to a pointer of a private type which is null if and only if the stored pointer is null. This is explained also at the reference above and it's the way boost::shared_ptr implements "conversion to bool semantics" (take a look at the source for inspiration).
OK I'll read it over throughly. Thank you for the link.
