|
|
AssignmentExpression[In, Yield] :
|
|
LeftHandSideExpression[?Yield] = AssignmentExpression[?In, ?Yield]
|
|

|
1. If LeftHandSideExpression is neither an ObjectLiteral nor an
|
|
ArrayLiteral, then

|
[...]
|
|
e. If IsAnonymousFunctionDefinition(AssignmentExpression) and
|
|
IsIdentifierRef of LeftHandSideExpression are both true, then
