The whole point of the exercise was to catch the "exceptional" situation 
in which _too much_ is pushed.  I am guessing you *did* need to dig a 
bit deeper (using your words).  See the original post again and try 
paying attention this time. :*)

That can be too deep for the OP.  The inquiry looked very much like a 
homework (done by the OP, which is commendable), part of a C++ course, 
in which they *might* learn later that an exception specification is 
frowned upon by some c.l.c++ inhabitants.
