 In addition to Python's normal set literals using curly braces, Coconut supports a special `s` (for `set`) or `f` (for `frozenset`) in front of a Python-like set literal to ensure it is a set literal of the specified type even when it otherwise would not be, such as when it is empty, or if a `frozenset` is desired.
