Depending on the language used sometimes you can even hide the type of the singleton instance in a function body (also assuming the PL support local static decls), so instead of having `TypeX.instance()` you can just have `xInstance()`.
Otherwise, the article does not mention the problem of race conditions but sometimes it might be better to use static constructors instead of performing lazy construction in the instance getter.
