It's all relative. I would consider a 10 somebody who could write the C++ compiler without guidance for example. And probably give myself a 4 as a result.

Would you only consider someone's knowledge of Python a 10 if they could write a Python interpreter without guidance?

I will give the creators of PonyORM a 10 as well.

It's really quite interesting that they build the queries from the AST. To contrast C# generates the Sql for Linq to Sql by building up an expression tree using the IQueryable interface.

This simplifies step one of the Pony ORM author's answer.

My point is the scale is absolute. Somebody who rates themselves a 9 on C++ knowledge probably doesn't realize how much there truly is to know. Sort of a corollary to the dunning-krueger effect.
