Consider this:
====
type
{ TRec }
TRec = record
// whatsoever
class operator Initialize(var aRec: TRec);
end;
{ TRec }
class operator TRec.Initialize(var aRec: TRec);
begin
writeln('class operator TRec.Initialize(var aRec: TRec)');
end;
function foo: TRec;
begin
writeln('foo');
end;
begin
foo;
end.
===
It outputs:
C:\Users\Bart\LazarusProjecten\ConsoleProjecten>test
class operator TRec.Initialize(var aRec: TRec)
foo
So, the initialization code is called before anything in the function.
