> makes the error message longer
Out of curiosity is there a guide as to what is considered a too long error message ?
Or is there a technical reason like after a certain length strings are not cached and exception will be slower to construct ? I'm trying to understand why rhettinger would have proposed in his talk to make this specific error message longer and there is a push back now.

Good point, would "or has been unset" be acceptable ?
