You are right, I don't know you beyond these online interactions. I was giving you the benefit of the doubt, but you sound very vindictive, and I get it, you know stuff. Building and designing things is a journey, it won't be perfect unless you set your expectations low.

I didn't just work on the scala plugin, I changed scalac to be completely incremental at the AST level (better than everything being a Diff[T]), which was no easy feat (nor did it last, but it worked and became its own tech [1]). I've dug deeper into scalac front end code (Typers, namers, parsers) than most scalac devs have; I know Martin's style very well as a result.

[1] work on making scalac incremental eventually led to http://research.microsoft.com/en-us/people/smcdirm/managedti...
