+  9. Return ! CreateArrayFromList( list ).
+
+  AvailableCurrencies ( )
+    The AvailableCurrencies abstract operation returns a List, ordered as if an
+    Array of the same values had been sorted using %Array.prototype.sort% using
+    undefined as comparefn, that contains unique, well-formed, and upper case
+    canonicalized 3-letter ISO 4217 currency codes, identifying the currencies
+    for which the implementation provides the functionality of Intl.DisplayNames
+    and Intl.NumberFormat objects.
