OK. But in 22 years, I've never had a desire to raise with custom args, and I've often had a desire to express inheritance relationships. So this need feels to me to be rare, at most (and probably usually an antipattern). That said, the ExceptionMaker that I proposed gets you exactly what you want already. I like Chris' idea of defaultdict and square brackets even better than mine about memoization (maybe with @functools.lru_cache). Either way, you already HAVE what you are asking for, except few people actually want to use it. -- The dead increasingly dominate and strangle both the living and the not-yet born. Vampiric capital and undead corporate persons abuse the lives and control the thoughts of homo faber. Ideas, once born, become abortifacients against new conceptions.
