Hello,

How do I use the TStringHelper with SysUtils functions?

When I've tried to compile this code:

=== code ===

program Project1;
{$mode objfpc}{$H+}
uses
  SysUtils;
begin
  WriteLn(ExtractFileExt(ParamStr(0)).Substring(1));
  ReadLn;
end.

=== /code ===

I've got:

project1.lpr(9,39) Error: Illegal qualifier

A possible fix would be changing the TStringHelper declaration from "TStringHelper = Type Helper for AnsiString" to "TStringHelper = Type Helper for string" keeping it Delphi compatible.

Thank you!
