Description

"19.1 Exception classes

1 The Standard C + + library provides classes to be used to report certain errors (17.4.4.8) in C + + programs. In the error model reflected in these classes, errors are divided into two broad categories: logic errors and runtime errors.

2 The distinguishing characteristic of logic errors is that they are due to errors in the internal logic of the pro- gram. In theory, they are preventable.

3 By contrast, runtime errors are due to events beyond the scope of the program. They cannot be easily pre- dicted in advance. The header <stdexcept> defines several types of predefined exceptions for reporting errors in a C + + program. These exceptions are related by inheritance."

From what POV po::unknown_option is 'due to errors in the internal logic of the program'? All po:: errors should be separated into two groups (runtime and logic) or std::exception should be used as a base class.

I'd like to see this fixed too.
