} I have noticed that every now and then `print -P "%~"` prints "~unambiguous".

} Haven't investigated any further... the $compstate assoc contains an
} element `unambiguous'. Maybe one of the recent changes to the
} parameter code...?

I don't know if it's one of the recent changes, but that does appear to
be the problem:

zagzig% setopt autonamedirs
zagzig% typeset -A foo
zagzig% foo[bar]=$PWD
zagzig% print -P %~
~bar

} And maybe we should add code to prevent the automatic name-dir
} behaviour for assoc elements anyway (if we don't have that already and 
} this is really the cause).

Actually, I have a longstanding request that ~foo[bar] should work ...
but that means changing the parser ...

Certainly assigning to foo[bar] shouldn't define ~bar.
