Can anybody explain this?

% cat tst
print $HOME/bin
print ~/bin
fdir='~/bin'
print ${~fdir}
setopt globsubst
print $fdir
% zsh -f ./tst
/home/user2/pws/bin
/home/user2/pws/bin
~/bin
~/bin

Why don't the last two give the same as the first two?  There's no rule
that says `parameter expansion doesn't work properly in non-interactive
shells', is there?  But it's there in 3.0.6-pre-2 as well, so maybe there's
something I'm just failing to understand.
