Good question. Three options I see:
- Before the label and binding names, where inout appears today, and where other argument modifiers like `@autoclosure` go: func foo(&label x: Int)
which is the minimal change.
- Before the binding name: func foo(label &x: Int)
which is problematic for implicitly-labeled arguments.
- Before the type name: func foo(label x: &Int)
This is the most definition-follows-use-y, but would be inconsistent with other argument modifiers.
