If that's the only issue, then don't use "dirs" at all; instead use
"print $dirstack" which *won't* include the current directory.

} But the "u" parameter solves it indeed! Thank you very much for pointing

One other thing that just occurred to me is that a single line of
output is unreliable when a directory name may contains whitespace.
You should use:

	print -l $dirstack > ~/.zdirs
and
	dirstack=( ${(uf)"$(< ~/.zdirs)"} )

} Is there any reason for why?

We're having a discussion about that over on zsh-workers right now.  My
position is that $dirstack is just a view on an internal data structure
that cannot be held responsible for the flags set on the parameter, and
therefore for consistency the parameter should not be allowed to have
flags that conflict with that internal structure (it happens to be a
linked list).

} I assumed I could treat dirstack as any other array since, well,
} the *manual* says dirstack is "a normal array".

I think "normal array" just means it's not an "associative array".

The only way to impose consistency with "typeset -U dirstack" on the
underlying internal structure would be to add

    chpwd() { dirstack=( ${(u)dirstack} ) }
