Interfaces aren't pointers, they are a value type (it's a tuple as you describe).

The distinction for typed nil is useful because some receivers may work with a nil value. This whole thread enumerates the disadvantages pretty clearly, but I just wanted to point out that it _can_ be useful.

I do think compiler warnings would be helpful when this kind of thing happens implicitly, to prevent new language users from being confused for extended periods.
