+/** (Deprecated) Generic exception
+ *
+ *  An error is defined by a category and a value within that category.
+ *
+ *  This used to be a structure for C exceptions but it has been retrofitted
+ *  as a C++ exception and some of its data has been moved in the
+ *  WithContextException base class. We should deprecate it and replace it
+ *  with either C++ different exceptions or `std::system_error` which already
+ *  provides this (category + error code) logic.
