I wonder if I could ask a silly question. My understanding is that

I note somebody at Embarcadero blogging [Paraphrase follows] "Delphi
is being enhanced by adding memory management features such as
reference counting".
Would there be any advantage in reimplementing strings as a tree of
classes, with the compiler doing appropriate things to change e.g.
Pos() into String.Pos(), UnicodeString.Pos() or whatever as appropriate?
String is the automatic reference-counted object.
But FPC team always denies this :))) citing Pascal standards of passed
century.
Btw
var
s:utf8string;
ws:UnicodeString;
i:=s.length();
ws:=s.convert(UTF-16);
much more readable and causes less headache.

Anton
