The probability of exception doesn't matter. Scope guards (or RAIIFunction) 
are typically used to implement exception safety, so introducing the 
possibility of exception from the scope guard itself sort of defeats its 
purpose. At the very least, it will complicate usage - probably, more than it 
will simplify one. IMHO, this tool should not be based on boost/std::function.
