Well, I am also of the opinion that threadvar is kind of a kludge too.
I think part of the aesthetic of Pascal is that it reads fairly close
to English. Creating a lot of new compound words is a bit jarring.
As I just now figured out how to articulate the above, I have what I
think is a more consistent group of proposals. It will prevent needing
to create a lot of special keywords:
var
c: thread TMyClass;
d: auto TMyClass;
Or, perhaps even better:
thread var
c: TMyClass;
managed var
d: TMyClass;
