And it's even simpler in case the output is to be captured and not 
echoed to stdout at all:

     body_list=( ${(@f)"$( highlight $filename )"} ) 2>&1 | read _err

If I do:

     body_list=( ${(@f)"$( highlight $filename > /dev/tty )"} ) 2>&1 | 
read _err

... I get the output to screen, so that answers my previous question.  
The syntactic logic might be harder than Finnish, but it *is* there.
