Doing the same conceptual thing using different syntax does not seem right as
generics, macros and other nice stuff become clumsy and too verbose.
See
//========================================================
program project1;
{$mode objfpc}
type
TRec= record
A:array of integer;
S:string;
end;
var R1,R2:TRec;
begin
SetLength(R1.A, 3);
R1.A[0]:=1;
R1.A[1]:=2;
R1.A[2]:=3;
R1.S:='123';
R2:=R1; // shallow copying <> full clone
R2.A[0]:=10;
R2.S[1]:='S';
// does not work as expected (no copy-on-write/cloning)
writeln(R1.A[0]); // prints 10
writeln(R2.A[0]); // prints 10
// works fine
writeln(R1.S[1]); // prints 1
writeln(R2.S[1]); // prints S
end.
