14.1.2 Static Semantics: Early Errors
StrictFormalParameters : FormalParameters
- It is a Syntax Error if BoundNames of FormalParameters contains any
duplicate elements.
FormalParameters : FormalParameterList
- It is a Syntax Error if IsSimpleParameterList of FormalParameterList is
false and BoundNames of FormalParameterList contains any duplicate
elements.
