Another example of why implicit conversions are evil. :-)

"operator const detail::undeletable* () const" will be used for the
comparison.

FWIW, I tend to agree with Darin that the if(f), f = nil, f == nil
constructs, while useful, are not strictly necessary (considering the
problems they introduce) - the explicit empty(), clear() methods are fine.
