I like the symmetry with the other anonymous types. This provides a highly focused tweak to Swift, with limited impact, and a measurable benefit to developers. (AKA the "Rule of Lattner")

Further, the values cannot be assigned to variables or passed as arguments as they have no "type".  I suspect it won't be hard to restrict them for being used with `Any` argument, limiting their use to flags and switch cases. If I'm conceptualizing this correctly, the benefits are clear and the consequences are small.
