Set

class Set[T](PyoSet[T]):
    """`Set` represent an in- memory **unordered**  collection of **unique** elements.

    Implements the `Collection` Protocol from `collections.abc`, so it can be used as a standard immutable collection.

    The underlying data structure is a `frozenset`.

    Tip:
        - `Set(frozenset)` is a no-copy operation since Python optimizes this under the hood.
        - If you have an existing `set`, prefer using `SetMut.from_ref()` to avoid unnecessary copying.

    Args:
            data (Iterable[T]): The data to initialize the Set with.
