      7 description: An ArrowFunction in global code may not contain `new.target`
      8 info: |
      9  - It is a Syntax Error if StatementList Contains NewTarget unless the source
     10    code containing NewTarget is eval code that is being processed by a direct
     11    eval that is contained in function code that is not the function code of an
     12    ArrowFunction.
     13 
     14  14.2.3 Static Semantics: Contains
     15 
     16  With parameter symbol.
     17 
     18  ArrowFunction : ArrowParameters => ConciseBody
     19 
     20  1. If symbol is not one of NewTarget, SuperProperty, SuperCall, super or
     21     this, return false.
     22  2. If ArrowParameters Contains symbol is true, return true.
     23  3. Return ConciseBody Contains symbol.
     24 
     25  NOTE Normally, Contains does not look inside most function forms. However,
     26       Contains is used to detect new.target, this, and super usage within an
     27       ArrowFunction.
