  B.3.3.1 Changes to FunctionDeclarationInstantiation

  1. If strict is false, then
    a. For each FunctionDeclaration f that is directly contained in the
       StatementList of a Block, CaseClause, or DefaultClause, do
      i. Let F be StringValue of the BindingIdentifier of FunctionDeclaration f.
      ii. If replacing the FunctionDeclaration f with a VariableStatement that
          has F as a BindingIdentifier would not produce any Early Errors for
          func and F is not an element of parameterNames, then
       ...
flags: [noStrict]
