    Module semantics: evaluation · 91e4e200

    Files whose name ends in `_.js` are not themselves valid Test262 tests
    and should not be interpreted as such by test runners.

    The tests for the GetBindingValue method of the module Environment
    Record are very minimal. This is because GetBindingValue is necessary to
    assert any aspect of binding creation/initialization/mutation. In this
    way, GetBindingValue is being implicitly tested by every test that
    references a binding value.

    8.1.1.5.1 GetBindingValue (N, S)

    [...]
    3. If the binding for N is an indirect binding, then
       [...]
    5. Return the value currently bound to N in envRec.


    15.2.1.16.4 ModuleDeclarationInstantiation( )

    [...]
    14. Let declaredVarNames be a new empty List.
    15. For each element d in varDeclarations do
        a. For each element dn of the BoundNames of d do
           i. If dn is not an element of declaredVarNames, then
              1. Perform ! envRec.CreateMutableBinding(dn, false).
              2. Call envRec.InitializeBinding(dn, undefined).
              3. Append dn to declaredVarNames.
