    For Async Tags apply will always run asynchronously but to cover cases where the operation might already be executed point is used.

    For Async Tags apply will always run asynchronously but to cover cases where the operation might already be executed point is used.

    Example:
    1. All SwayDB writes occur synchronously using IO. Running completed IO in a Future will have a performance cost. point is used to cover these cases and IO types that are complete are directly converted to Future in current thread.
