I think it is sometimes not appropriate to terminate right away when you run
into a program logic error. E.g. if you detect one during a customer
transaction in an ATM application you would want to _try_ returning the card
back to the customer before you terminate and restart. That's why I believe
the distinction between std::runtime_error and std::logic_error is actually
no so bad. By convention, you can catch a std::runtime_error anywhere and
attempt a remedy. A std::logic_error however must always lead to a program
exit, so you catch it only to perform important last-minute actions and
rethrow afterwards.
