Sorry, please bear with me.
I think this is just a precedence issue I raised. If TWrapper has a + operator
then:
wrapper := wrapper + 1
should call the + operator, because base class takes precedence over the field
num: integer. Correct? If TWrapper doesn’t have a + operator then:
wrapper := wrapper + 1 should resolve to wrapper.num := wrapper.num + 1
right?
type
TWrapper = record
num: integer;
property _default: integer read num write num; default;
class operator + (left: TWrapper; right: integer): TWrapper;
end;
