I stand corrected. I've checked Delphi5 today and none of my
expectations where correct :-(
Of course I think that AnsiString being a native type would require
that (one) typecast just like any other (native type).

Of course I also think that any object should be cast to a mininum
common ancestor before being cast to any other class, but maybe it's
just me ;-)
