Like I said, I just had the pleasure of moving a small codebase (less than 2,000 lines of code) from Boo to C#, and I can tell you, the C# Compiler is really stupid. I sometimes feel as if I had to speak to an idiot. You do A, and then do B, and then do C, and then... Argh!
Perhaps the biggest compliment that I can give to Boo is that I flat out refuse to work for any length of time with C# without Resharper. I often write Boo code in notepad, and I am talking about non trivial applications.
