As will I. Over 1,000+ pages of source is believable and still one hell of an accomplishment at the quality level. I still consider the possibility that the stack included specs of successful or error states given the importance of those for a working program. I know she liked including tons of error handling in everything. Most might have done that with tests but she did it in primary stuff. So, there&#x27;s room for stuff in there that&#x27;s not pure source as modern developers would consider.
