In what way is this a "SQLite clone"?
Mad props to the author. Many Python programmers never had proper training in computer science, so it is encouraging to see people filling in the gaps of their knowledge.
Someone in our community built something and had the courage to release it. Your criticism is unfair.
I think it doesn't even get close to being a criticism, and it's certainly unclear if the goal is to literally clone SQLite or to implement SQLite-ish. This is a fair question.
