However it would be nice to have a feature like
property Foo[Index: Integer]: Integer write SetFoo read GetFoo;
property Foo[Index: Integer; Ask: Boolean]: Integer write
SetFooAsk read GetFooAsk;
The must have different Method Names, because the Setters(write SetFoo)
last argument is the Value, so it' can not have a optional Ask element:
procedure WrongSetFoo(Index: Integer; Ask: Boolean= True; AValue:
But with different Setter/Getters that would not be a problem. In fact
they can have the same name, if they are overloaded.
Any idea if such a feature would have a chance?
