What about local variables? as in


Procedure p1;
Var
    v1 : integer;
    v2 : boolean;


    Procedure p2;
    begin
        ... { v1 and v2 are visible here }
    end;
Begin
    ...
End;


presumably p2 has to be moved to outside p1 and renamed, but the
variables v1 and v2 cannot be moved out like that - what if procedure
p1 is recursive?


Do you make local variables into a struct, and pass a pointer to that
when calling p2?
