In the Lumiera code base, we use C-String constants as unique error-IDs. Basically this allows to create new unique error IDs anywhere in the code. However, definition of such IDs in arbitrary namespaces tends to create slight confusion and ambiguities, while maintaining the proper use statements requires some manual work. Thus I introduce a new **standard scheme** * Error-IDs for widespread use shall be defined _exclusively_ into `namespace lumiera::error` * The shorthand-Macro `LERR_()` can now be used to simplify inclusion and referral * (for local or single-usage errors, a local or even hidden definition is OK)
