[fpc-pascal] Re: Use generic class as parameter (was: how to write enumerator for trees)

[Xiangrong Fang]

I got this error now:

treap.pas(311,48) Error: Illegal expression
treap.pas(311,50) Error: Illegal expression
treap.pas(311,50) Fatal: Syntax error, ";" expected but "ordinal const"
found
Fatal: Compilation aborted

The line that generated this error is:

  if Result = NullNode then begin
    if (Rank = 0) or (Anchor < Key) then Rank += 1;   <-- error here
    Result := nil;
  end;

It seems that the += operator is not supported anymore??  Is there any
switches in the new 2.7.1?
