There was some discussion WRT that issue months ago. Currently the
implementation is wrong IMHO. When $hash{key} doesn't exist a new
PerlUndef is returned (which is fine) but it should be stored in the
hash too, so that assigning to $foo does The Rigth Thing.
(Parrot aggregates have reference semantics, so ...)

I can imagine, that these get a different vtable which propagates
taintness on.
