Multidimensional conformant arrays

I think I found a bug with conformant arrays.

Are conformant arrays supposed to work in multiple dimensions at all?
If so, the following program gives the wrong result "3 2 1 2" instead of
"1 2 3 4"; if not, it doesn't generate a necessary error message...

program x;

procedure p(var a:array[b..c:integer;d..e:integer] of integer);
begin
 writeln(b,' ',c,' ',d,' ',e)
end;

var a:array[1..2,3..4] of integer;
begin
 p(a)
end.

The corresponding program using a schema type works.

BTW: Wouldn't it seem reasonable to allow the "with" statement also for
schema types, as in the following example:

program x;
type t(a:integer)=array[1..a] of integer;

procedure p(var v:t);
begin
 with v do writeln(a)
end;

begin
end.

And one little detail: The next program gives the error message

x.p:6: request for member `X' in something not
x.p:6: a record, schema or object

which is not completely correct since v is a schema, but x is not a field
of v.

program x;
type t(a:integer)=array[1..a] of integer;

procedure p(var v:t);
begin
 writeln(v.x)
end;

begin
end.
