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
