class Get_caller:
    """A reemote operation that returns the instance that initiated the command.

    This class is designed to be used within the reemote framework to allow
    a script to get a reference to the specific object that is currently
    executing. It is useful for introspection or for passing the object
    instance to other functions.

    The operation works by yielding a local `reemote.command.Command` that is
    constructed with the instance itself as the `caller` argument. An
    internal callback then returns this `caller` as the result of the
    command's execution.
