In my .zprofile, I have to use a command similar to this one in order
to set-up my environment.
eval `some_command | command_filter`
My problem is that some_command is written for ksh/sh and I do not
have the sh_word_split option set. This causes the above command to
fail.
It complains with the following error message:
zsh: no such file or directory: /usr/bin/X11/resize -u
which is clearly because of the sh_word_split option unset.
As a work-around, I did the following:
setopt shwordsplit
eval `some_command | command_filter`
unsetopt shwordsplit
which works fine. The problem with this is that it is not elegant and
can be potentially dangerous if ever change my mind about having
shwordsplit option unset. I know I could query the original state of
the option and only to this setopt/unsetopt if the option was
originally unset.
By looking at the man page, I thought I could use something like this:
eval ${=$(some_command | command_filter)}
but it fails the same way.
I am using zsh 3.0.2 on a HP 715 with HP-UX 9.05. Zsh has been
compiled with the native HP cc compiler.

Hmmm ...
% echo $ZSH_VERSION
3.1.0
% unsetopt | grep shwordsplit
shwordsplit
% cat =foo
#!/sbin/zsh
echo 'ls -x'
% eval `foo`
... output of ls -x follows ...
Could you be more specific about your command? E.g.
% CMD='ls -x'
% eval `$CMD`
zsh: command not found: ls -x
