Exactly. A resistor R can be assumed in series with the switch,
and the energy dissipated on R can be derived (easy). The resulting equation
will show that the energy dissipated is R independent. One half of
the original energy of the system will be lost on R, regardless of its
value. If L is assumed instead of R, we can arrive at the same
conclusion except that the 1/2 energy will not be lost, but will 
be stored in the inductor regardless of its value.
