    8. Let R be the result of performing CaseBlockEvaluation of CaseBlock with
       argument switchValue.
    9. Set the running execution context’s LexicalEnvironment to oldEnv.
    10. Return R.

    CaseBlock : { CaseClausesopt DefaultClause CaseClausesopt }

    1. Let V = undefined.
    2. Let A be the list of CaseClause items in the first CaseClauses, in
       source text order. If the first CaseClauses is not present A is « ».
    3. Let found be false.

    5. Let foundInB be false.
    6. Let B be the List containing the CaseClause items in the second
       CaseClauses, in source text order. If the second CaseClauses is not

    11. If R is an abrupt completion, return Completion(UpdateEmpty(R, V)).
