* Yet another way to achieve it is
print *(/)
or
echo *(/)
Update
* A bit more correct version (as noted by @Stéphane Chazelas) would be
print -rl -- *(/)
or
echo -E - *(/)
respectively to take care about spaces and escape sequences inside filenames.
* Yet even more correct version is print -rN which takes care of linebreaks inside filenames by separating the results with nulls, for example:
print -N *(/) |xargs -0 -n1 -i echo cp {} {}~
which is a "preview" version of creating a backup of all subdirectories in current dir.
