An uninterned symbol is not the same as any other symbol, even one with the same name. These symbols are useful in macro programming and in other situations where guaranteed-unique names are needed. A lexical syntax for uninterned symbols is described, allowing uninterned literal symbols to appear in program source and macro templates. A survey of uninterned and uniquely-named symbols in Scheme is also provided.
