Weird expansion issue with (D)

Weird expansion issue with (D)

I think I might have discovered a bug in the (D) expansion of named
directories, and I'm not sure how to sort this out.

    $ echo "${(D)PWD}"
    ~CODE_AUDIT_HELPERS

    $ var=$PWD/install.zsh

    $ ls $var
    /Users/zachriggle/.zprezto/modules/code-audit-helpers/install.zsh

    $ echo "${(D)var}"
    ~var

Any ideas on what's happening here?  This is on zsh 5.8.1

This is working as expected assuming you've enabled auto_name_dirs.
This isn't the kind of option I would recommend enabling unless you
really know what you are doing.

Shouldn't the output be

~CODE_AUDIT_HELPERS/install.zsh

?

Actually nevermind, I see now that using the variable "var" is being
expanded, duh.

Is there any way to mark a specific variable name to NOT be expanded in
this way?

Nope.

Are you sure you need auto_name_dirs? Perhaps you can use regular
named directories instead? If not, what's your use case that requires
auto_name_dirs?
