> ridiculous breaking change

Not at all. This can be done without breaking code. The important part isn't typing the namespace - rather, the freedom to move files around without having to change namespaces.

Even if it were something like:

  auto namespace; // for example

it's good enough. Allows me to move directories around, without having to depend on an IDE to keep namespaces in sync. IDEs anyway can only take a good guess at this, if namespace doesn't match the dir name.

I am not looking for a scripting solution. C# is a misfit for it. I want all of C#, with terseness and not forcing OOP.
