/**
 * @assertion An entry element (the base case in maps):
 *
 * It is a compile-time error if the key and value expressions are not constant
 * expressions.
 *
 * As is already the case in Dart, it is a compile-time error if the key is an
 * instance of a class that implements the operator == unless the key is a
 * string, an integer, a literal symbol or the result of invoking a constant
 * constructor of class Symbol. It is a compile-time error if the type arguments
 * of a constant map literal include a type parameter.
 *
 * The expansion is the entry formed by the key and value expression values.
 *
 * @description Checks that it is a compile-time error if the type arguments
 * of a constant map literal include a type parameter.
