We'd really like to say that private decls can't affect other files,
but we don't have enough information at parse-time:
- Private members of non-private classes still show up in vtables,
which affects subclasses and callers in other files.
- Private stored properties of non-private structs change the
layout of the struct.
- Private types may be used in private stored properties, affecting
the layout of the containing struct.
- Private decls of /any kind/ can be used as the initial value of a
stored property without an explicit type.
private class Evil {
class func defaultAlignment() -> Alignment { return .evil }
}
public struct Character {
// Inferred type here!
private var alignment = Evil.defaultAlignment()
}
To be safe and correct, go back to only ignoring method bodies.
