pretty sure that's a syntax error.  and for simple variables, quite
wrong.  this function does better, but still screws up a few things.

 v=() for(v in `{cd /env; ls -Q}){
        if(~ $v *'#'*)
                . /env/$v
        if not x=() if(! ~ $v pid status '*' ifs){
                # f015; plan 9 raw alt
                ifs=() eval $v '= (' `{tr '\00' ''  < /env/$v >/tmp/fubar ;
                        echo '  ,s:'':'''':g
                                ,s::'' '':g
                                ,s:(\n|[^])+:''&'':g
                                ,s:: :g
                                ,p' |
                        sam -d /tmp/fubar >[2=]
                        } ')'
        }
}

the easy (and correct) answer is
        exec rc
