* Simplify conforming to ExpressibleByStringLiteral with default implementations * attributes on default implementations * ExpressibleByUnicodeScalarLiteral validation test * more generic default implementations * clean up test * remove unneeded implementations * remove test verification * indent * revert @effects and affected methods * fix test generics with _ protocols * Add semantic tests * clean up tests * Fix redundant conformance requirements
