VariableDeclaration : BindingPattern Initializer
1. Let rhs be the result of evaluating Initializer.
2. Let rval be GetValue(rhs).
3. ReturnIfAbrupt(rval).
4. Return the result of performing BindingInitialization for
BindingPattern passing rval and undefined as arguments.
AssignmentElement[Yield] : DestructuringAssignmentTarget Initializeropt
[...] 7. If Initializer is present and value is undefined and
IsAnonymousFunctionDefinition(Initializer) and IsIdentifierRef of
DestructuringAssignmentTarget are both true, then
a. Let hasNameProperty be HasOwnProperty(v, "name").
b. ReturnIfAbrupt(hasNameProperty).
c. If hasNameProperty is false, perform SetFunctionName(v,
GetReferencedName(lref)).
