Description copied from class: ExpressionWithChildState
combines half-made expression and newly found child expression into the expression.

Say this container has three child expression exp1,exp2, and exp3. Then, the expression of this state will be made by the following method invocations.

   annealExpression(
     castExpression(
       castExpression(
         castExpression(null,exp1), exp2), exp3 ) )
