hmm I would have thought that String and PackedString should behave 
identical, apart from the 'packedness'. Still there could be some subtle 
semantic difference ...

Yeah. Yhc was developed from nhc98, which for some strange reason liked 
to reverse strings sometimes. We've never really discovered why and have 
avoided trying to fix it, so it's just sort of stayed that way.

But be assured, it's just as confusing to us as it is to you ;-)
