## Una *instance* "callable"

En Python hay una forma de hacer que una instance de una clase sea un "callable".

No la clase en sí (que ya es un callable), sino una instance de esa clase.

Para hacer eso, declaramos un método `__call__`:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[12] *}

    return withParameters(attribute, ImmutableSet.of(value));
  }

  /**
   * Returns a new instance with the same type and subtype as this instance, with the {@code
   * charset} parameter set to the {@link Charset#name name} of the given charset. Only one {@code
   * charset} parameter will be present on the new instance regardless of the number set on this
   * one.
   *

    /**
     * Creates and returns a new instance of {@link ArrayDeque}.
     *
     * @param <E> the element type of {@link ArrayDeque}
