In the example below, the plugin is coded in the `other.gradle(.kts)` script file.
Then, the `other.gradle(.kts)` is applied to `build.gradle(.kts)` using `apply from`:

### When to Use

            if (any.cardinality() > 0 && any.cardinality() != candidateCount) {
                // there is at least one candidate which does NOT provide this attribute
                remaining.andNot(any);
                if (remaining.cardinality() == 0) {
                    // there are no left candidate, do not bother checking other attributes
                    break;
                }
            }
        }
    }

        def dir3 = parent.createDir("dir3")
        def other = parent.createDir("dir4")
        def child = dir1.createDir("child1")
        def multi = from(dir1, dir2)

        expect:
        def s1 = multi.plus(dir3)
        s1.contains(dir1)
        s1.contains(child)
        s1.contains(dir2)
        s1.contains(dir3)
        !s1.contains(other)
        !s1.contains(parent)

  public static <E> ImmutableList<E> of(
      E e1, E e2, E e3, E e4, E e5, E e6, E e7, E e8, E e9, E e10, E e11, E e12, E... others) {
    checkArgument(
        others.length <= Integer.MAX_VALUE - 12, "the total number of elements must fit in an int");
    Object[] array = new Object[12 + others.length];
    array[0] = e1;
    array[1] = e2;
    array[2] = e3;
    array[3] = e4;
    array[4] = e5;
    array[5] = e6;

    * `dict`

    And the same as with Python 3.8, from the `typing` module:

    * `Union`
    * `Optional`
    * ...and others.

=== "Python 3.8+"

    * `List`
    * `Tuple`
    * `Set`
    * `Dict`
    * `Union`
    * `Optional`
    * ...and others.

### Classes as types

You can also declare a class as the type of a variable.

// List of some generic middlewares which are applied for all incoming requests.
var globalMiddlewares = []mux.MiddlewareFunc{
	// set x-amz-request-id header and others
	addCustomHeadersMiddleware,
	// The generic tracer needs to be the first middleware to catch all requests
	// returned early by any other middleware (but after the middleware that
	// sets the amz request id).
	httpTracerMiddleware,
