/**
 * @assertion Let d be the declaration of a variable v.  If d is a local or
 * instance variable, then the invocation of the implicit getter of v
 * evaluates to the value stored in v.
 * If d is a static or library variable then the implicit getter method of v
 * executes as follows:
 * - Non-constant variable declaration with initializer. If d is of one of the 
 *   forms var v = e; , T v = e; , final v = e; , final T v = e; , static 
 *   v = e; , static T v = e; , static final v = e;  or static final T v = e; 
 *   and no value has yet been stored into v then the initializer expression 
 *   e is evaluated. If, during the evaluation of e, the getter  for v is 
 *   invoked, a CyclicInitializationError is thrown. If the evaluation 
 *   succeeded yielding an object o, let r = o, otherwise let r = null. In 
 *   any case, r is stored into v. The result of executing the getter is r.
 * - Constant variable declaration. If d is of one of the forms const v = e; ,
 *   const T v = e; , static const v = e;  or static const T v = e; the result
 *   of the getter is the value of the compile time constant e. Note that a
 *   compile time constant cannot depend on itself, so no cyclic references 
 *   can occur. Otherwise
 * - Variable declaration without initializer. The result of executing the
 *   getter method is the value stored in v.
 * @description Checks that the initializer expression is evaluated at
 * the first use of a static variable.
