class ShouldIReally
{ 
    public: 
        class NoIShouldnt
        {
            // intentionally empty
        };
        ShouldIReally() 
        { 
            if (yes()) 
                okLetsDoIt(); 
            else 
                throw NoIShouldnt();
        } 
};
int main() 
{
    try
    {
        ShouldIReally s;
        // if you arrive at this line, s is fully constructed
    }
    catch (ShouldIReally::NoIShouldnt &)
    {
        // if you arrive at this line, s threw an exception
    }
}
Above the most simple sample code that came to my mind.
If  the  constructor  called the base class constructor or constructed
some member variables before throwing the exception,  the  constructed
(sub)objects  will  be  destructed before the constructor is left; but
the SouldIReally destructor will not be called since s  is  not  fully
constructed when the exception is thrown.
