<p>During the process of working with the API, user information is accumulated in the DC with which the user is associated. This is the reason a user cannot be associated with a different DC by means of the client. However, in the future, during prolonged communication from an unusual location, we may decide that the user’s data must be moved to a different DC. After some time, the data will be copied and the association will be updated. Once this happens, when executing any query transmitted to the old DC, the API will return the USER_MIGRATE_X error. The client will then have to establish a connection with the new DC and repeat the query.</p>

<p>In view of the importance of the construction presented above, it is built into the TL language in the following manner. A substructure in the form of [ <em>array-field-name</em> ":" ] [ <em>nat-ident</em> "<em>" ] "[" </em>field-descr<em> ... "]” may be used in the declaration of any combinator, where </em>nat-ident* is the name of any previously encountered field of type # (if it is not explicitly indicated, the most recent is used). In abstract, this substructure is equivalent to:</p>

<p>For example, in <code>cons {X:Type} hd:X tl:(list X) = list X</code> the parameter <code>X</code> may be made optional, because it is located at the very beginning of the argument list and is unambiguously determined by the <code>list X</code> result type. Similarly, in <code>tcons {X:Type} {n:#} hd:X tl:(%Tuple X n) = Tuple X (S n)</code> the values of X and n are completely determined based on the <code>Tuple X (S n)</code> result type, therefore they made be made optional parameters.</p>

<p>It usually makes sense to move all of a constructor’s arguments satisfying the second condition to the beginning of the list, arrange them in the order they appear in the result type’s parameters, and make them optional. Given such an approach, the full version of a constructor is rarely needed -- only when we want to transmit the value of the polymorphic or dependent type as a value of type Object. In all other cases, the type of the expected value from the context is already known, which means that all optional parameters can be recovered during decomposition.</p>

<li>The type <code>True</code> with a single null constructor <code>true</code> plays a role similar to the void type in C/C++. It is especially useful as a bare type <code>%True</code>, alias <code>true</code>, because its serialization has zero length.
