B.3.3.1 Changes to FunctionDeclarationInstantiation
[...]
2. If instantiatedVarNames does not contain F, then
a. Perform ! varEnvRec.CreateMutableBinding(F, false).
b. Perform varEnvRec.InitializeBinding(F, undefined).
c. Append F to instantiatedVarNames.
[...]
B.3.5 VariableStatements in Catch Blocks
[...]
- It is a Syntax Error if any element of the BoundNames of CatchParameter
also occurs in the VarDeclaredNames of Block unless CatchParameter is
CatchParameter:BindingIdentifier and that element is only bound by a
VariableStatement, the VariableDeclarationList of a for statement, or the
ForBinding of a for-in statement.
