So basically make a file like an object? :slightly_smiling_face:

Huh, I guess that is basically what I'm asking, isn't it. I'm mostly interested in the constructor part, though it's really not a big deal.

There's a potential problem with accidental overrides in Java, same as with `internal`. For `internal` it is resolved with name mangling, which is a kinda compromise. 

Hm, it seems I haven't really thought this proposal through. It seems most of my proposals seem like a good idea at the time, but end up being anything but on closer inspection.

Swift has this and it's very useful for nested functions that have to be called from extension functions or private classes
