// MARK: - Extensions
//
// Extensions are externally visible if they extend a public type and (1) have
// public members or (2) declare a conformance to a public protocol.
//
// Extensions without explicit availability that are externally visible use an
// implied floor of either the availability of the extended type or the
// deployment target, whichever is more available. This is a special rule
// designed as a convenience to library authors who have written quite a bit of
// code without annotating availability on their extensions and getting away
// with it because previously the deployment target was always used as the
// floor.
//
// Extensions without explicit availability that are not visible externally are
// checked using an implied floor of the deployment target.
