String interpolation with {..} give strange result

[magol]

I accidently write following interpolation string which gave a strange result

Console.WriteLine($"Content of {..} is strange");

The output is

Content of 0..^0 is strange

I cannot see that this is what it should do. It should be a compilation error.

The syntax .. is shorthand for an unbounded range or Range.All.

Ok. So I guess that's how it's supposed to be.
