He said: "Wow, O2 is just a great REPL engine for C# and Security Analysis"
I was like Rewhaaattt????
It turns out that the O2 Scripting environment is actually something called REPL which stands for: Read - Eval - Print - Loop (see http://en.wikipedia.org/wiki/REPL for more details).
And he is correct, the core of O2 is its ability to easily allow this loop to occur (for more details see these blog posts).
Note that I current write O2 in O2's REPL environment, because in comparison, the normal Visual Studio compilation process is SOOOOOOO painful (Usually I use O2's own development environment (IDE), but recently I created a VisualStudio AddIn for O2, so now I get the best of both worlds)
