Biggest problems with records is that we can’t make arrays of records because
the [] property copies the record with the getter (my other email on this never
got posted). If there was a feasible way to fix that problem then dynamic
arrays would be nearly obsolete anyways (probably still faster though).
var
A: TAlignedArray<TPoint>;
begin
A.Length := 1;
A[0].x := 100; // Doesn’t work, writes to a copy and never mutates the
underlying structure.
Is there no other way to specify alignment? It would be ugly but a compiler
directive could be used.
var
{$push}
{$dynamic-array-align 4096}
a: array of integer;
{$pop}
begin
SetLength(a,10); // just use normal SetLength now
