+ written with this in mind. This is done for two reasons. First, the
+ code sometimes doesn't work (possibly because the In_Instance test
+ is not specific enough - it probably should be testing to see whether
+ we are in an instance of the particular generic in which the result
+ of calling Corresponding_Generic_Type was declared) and causes correct
+ code to be rejected. Second, the code seems to no longer be necessary
+ (possibly because of subsequent fixes in this area which are not
+ specific to unary operators).
