[zsh] How to mimic errexit within subshell (or function)?

Show all headers | View raw

The following scheme doesn't work as expected: despite the set -e
(errexit), the subshell does not exit on error (it just goes on to
execute the next command):

#!/usr/bin/zsh
(
  set -e
  cmd0...
  cmd1...
  cmd2...
  ...
  echo "$0: done" 
) || { echo "$0: failed" && exit 1 }

How can I mimic the behavior of "set -e" within a subshell?  (Or
within a function, for that matter?)  (I realize that I can always
append "|| exit 1" to every command, but this is precisely what
I'd like to avoid.)

Thanks!
