Littering your code with throwing destructors is not the best practice, either.

The simple rule to follow is: don't ever throw in destructors. In
practice this means that destructors should free resources and do
nothing else. That way you don't litter destructors with try
catch(...), you use this only as a last resort means to prevent a
destructor from throwing.
