[swift-evolution] [Proposal] Eliminating Swift's Screaming Snake Case Identifiers

[Greg Titus]

You could make these identifiers act like {get set} vars in order to support the current behavior of #line. E.g. LLDB and playgrounds would use `#line = 12; #file = “foo.swift”` instead of `#line 12 foo.swift`.
