[swift-evolution] SE-0025: Scoped Access Level, next steps

[Brent Royal-Gordon]

> If Scala style access modifiers were adopted for Swift then a private(file) modifier would also be necessary to give the current private functionality.

I could imagine having these options:

	public							// visible to all everyone
	private(scope-name, scope-name, …) 	// visible to specified scopes (plus current scope)
	private							// visible only to current scope

scope-name could perhaps be:

* A type name (or Self, which would mimic C++-style private, or perhaps even C++-style protected depending on how we treat inheritance)
* A module name (or #module for the current module)
* A file name string (or #file for the current file)

And then the default would simply be `private(#module)`.

Alternatively, the parameterized level could be given a different name, like `internal` or `shared`. If that were the case, then `#module` might simply be the default.
