8. For each d in varDeclarations, in reverse list order do
|
|
a. If d is neither a VariableDeclaration or a ForBinding, then
|
|
i. Assert: d is either a FunctionDeclaration or a
|
|
GeneratorDeclaration.

iv. If fn is not an element of declaredFunctionNames, then
|
|
[...]

3. Insert d as the first element of functionsToInitialize.

|
|
15. For each production f in functionsToInitialize, do
|
|
a. Let fn be the sole element of the BoundNames of f.
|
|
b. Let fo be the result of performing InstantiateFunctionObject for f
|
|
with argument lexEnv.
