<p>
The iteration values are assigned to the respective
iteration variables as in an <a href="#Assignments">assignment statement</a>.
</p>

<p>
The iteration variables may be declared by the "range" clause using a form of
<a href="#Short_variable_declarations">short variable declaration</a>
(<code>:=</code>).
In this case their types are set to the types of the respective iteration values

<a href="#Satisfying_a_type_constraint">satisfy</a> the constraint of its respective
type parameter.
</p>

<p>
Each such pair of matched types corresponds to a <i>type equation</i> containing
one or multiple type parameters, from one or possibly multiple generic functions.
Inferring the missing type arguments means solving the resulting set of type
equations for the respective type parameters.
