Subject: zsh needs try-finally

Hi.
Zsh needs a mechanism a la Java's try-finally or lisp's unwind-protect.
Example:
for file in $*
do
tmp=$file.TMP-$commandName
mv -f $file $tmp
(eval $filter) < $tmp > $file
rm -f $tmp
done
The 'rm -f $tmp' command should be in a finally block, something like this:
for file in $*
do
tmp=$file.TMP-$commandName
mv -f $file $tmp
try
(eval $filter) < $tmp > $file
finally
rm -f $tmp
yrt
done

Thanks
Dave
