Inside the type I have:
TAlignedArray = record
public
type
TReference = ^T;
TValue = T;
...
procedure Push(const Item: TValue);
function Pop: TValue;
property Length: Integer read FLength write SetLength;
property Reference[Index: Integer]: TReference read G

Really, how? [] property uses a getter which copies the array right? I’mm not
aware of how to do this in Pascal without pointers.
Regards,
Ryan, actually ...
A.Length := 1;
A[0].X := 100;
... does work in my implementation.

Using array + operators there is no possibility to set alignment.

Gareth,
There is a bounty for this? I wonder if my solution is acceptable.
Also, my solution, or any for that matter, could be enhanced to make the
alignment size configurable per each array aligned array. That is, memory
alignment starting position and page size could be defined by each array.

I wonder if there's any incentive to have such a feature in-built in the
compiler. The bounty on #34031 has probably expired by now. If not,
then your unit would be a great addition.
Page-aligned memory is probably something that warrants further discussion
with the core team.
Gareth aka. Kit
