} However if the command outputs something, one loses the output.

I didn't really mean to imply that you should use this, just that some
of the plumbing is in place if we wanted to provide direct control.

On the other hand:

foreach foo (a b c) { print $foo; sleep 5 } | while { read -rE } { : }

(Using shortloops syntax to emphasize zsh-ness of this trick.)
 
} But with the encapsulation (to save typing), this is very limited.

As a hack, one could do:

    alias -g NOSUSP='|while { read -rE } { : }'

    foreach foo (a b c) { print $foo; sleep 5 } NOSUSP

This is similar to the "alias -g M='|more'" trick that I know a number
of people have used at one time or another.
