'''locals''' is a reference to the set of local variables. It's a map where each key is an identifier string, and the value is the value of that variable.

Because assignments and identifier look-up always try local variables first anyway, explicit use of the '''locals''' function is rarely needed.

One common use in [[Mini Micro]] is to tell whether an [[import]] module is being actually being run as the main program. In such a case, it will be true that <msinline>locals == globals</msinline> at the file scope (i.e. not inside any explicitly defined function). For examples, look at the bottom of any module in '''/sys/lib'''; when loaded and run directly, these modules run unit tests or otherwise do something useful.
