I don’t disagree with anything you’re saying but this is going to make for-in
loops much harder to work with. Pascal isn’t like C++, C#, Python etc… where
there are “auto” vars we can use for the iterator. Since I don’t want to
typecast every single time I access the iterator I’m probably going to make a
temporary iterator and then assign it to the real variable inside the loop.
var
it: pointer;
obj: TObject;
begin
for it in list do
begin
obj := TObject(it);
// continue on like before using “obj” instead of “it"
end;
That’s our realistic best use case now but it requires 2 extra steps. I hope
there’s a better solution to keep the for-in loops as easy to use as before.
