Productivity might be the wrong word. Discipline, grit, perseverance?
I've written parsers/lexers/code generators by hand for much smaller toy languages with no thought about performance at all and those were huge undertakings for me. I was just trying to convey my impressedness with some numbers that we can relate to somewhat.
But yeah, he has a "net" loc contribution of 284-148 = 136k lines of code. Assuming the code base is resonable (which I don't doubt), it's a pretty big project which he has built, which I'm impressed by.
