Is there a glob for files with names of e.g. exactly thirty
characters? sort of the equiv of /^.{30}$/

I don't know whether there's a more concise one, but this works to `ls`
the ones that match:
ls -l *(e:'[[ $#REPLY == 30 ]] || reply=()':)
You could also wrap the expression there into a function:
globlen() { [[ $#REPLY == $GLOBLEN ]] || reply=() }
GLOBLEN=30
ls -l *(+globlen)
More info:
man zshall | less +/estring

Best,

Yes. See zshexpn(1) for (#cN,M).
Example:
% ls -lad ls -lad /?(#c3)
drwxr-xr-x 2 root root 4096 Nov 2 23:31 /bin
drwxr-xr-x 15 root root 3460 Nov 22 23:12 /dev
drwxr-xr-x 161 root root 12288 Nov 22 14:20 /etc
drwxr-xr-x 14 root root 12288 Oct 22 09:43 /lib
drwxrwxr-x 8 root staff 4096 Nov 13 22:26 /mnt
drwxr-xr-x 4 root root 4096 Oct 4 11:05 /opt
drwxr-xr-x 4 root root 4096 Apr 29 2010 /srv
drwxr-xr-x 12 root root 0 Oct 22 09:50 /sys
drwxrwxrwt 22 root root 12288 Nov 23 09:15 /tmp
drwxr-xr-x 15 root root 4096 Oct 3 12:31 /usr
drwxr-xr-x 16 root root 4096 Jul 1 19:41 /var

I can't get this to work. It's new in 4.3.5, right, so it should be in 4.3.9?
I don't understand the commandline you gave (is there a paste error in
it?) and when I try it, I get "zsh: unknown file attribute".
