StrictFormalParameters : FormalParameters
|
|

|
- It is a Syntax Error if BoundNames of FormalParameters contains any

FormalParameters : FormalParameterList
|
|
|
|
- It is a Syntax Error if IsSimpleParameterList of FormalParameterList is
|
|
false and BoundNames of FormalParameterList contains any duplicate
|
|
elements.
