Indeed, contributions to Delphi 2009 syntax are welcome. I don't own any
Delphi now, so I can only offer applying the patch if someone will
submit one :)

For starters, just to make it basically parsed, I would even accept a
patch that parses it dumbly and places class name =
"TObjectList<MyClass>". That is, the simplest approach to just treat
whole "TObjectList<MyClass>" as a single identifier, without linking it
to the generic TObjectList. Of course, a better patch would be most
welcome ---I'm just saying that any crude solution will be accepted in
the meantime (as long as it doesn't break any normal parsing of course).

DoDi: remember that bug submitters do not have to be subscribed to
mailing list, so it's best to answer by adding a comment to the bug. (In
this case Thomas is subscribed, just mentioning...).
