In C# I'd like to able to :

- declare a namespace for the file (no indentation)

- declare that the file is a class and can only contain one (top level) class (still no indentation)

- `using` statements that don't import every symbol into my namespace :

    using System.Console;
    ...
    Console.WriteLine();

instead of :

    using Sytem;
    ...
    Console.WriteLine(); // where does "Console" come from ? god/IDE only knows

But yes, no to top-level programs.

But alreay with these few changes, I've saved 10% of the 80 columns width. I've made it easy to read a file without an IDE. You can start to write actual code at indentation level 0. I've made it easy to have one class per file and hard to have two class per file, in the spirit of making good pratice easy and bad practice hard.
