Bi and up. > A normal filehandle can already handle bidirection. Yes, but to exploit that would be something of a perversion: the in and out handles are very separate as far as everybody else is concerned. > I think the following solution suffices in a clean way: > > $h = open a pipe; > > Now, > $h.in; > $h.out; > $h.err; > > $h.print("foo"); # use $h.out > $l = $h.readline; # use $h.in Yes, if $h is the not-very-primitive version of IO. Surely the type of $h.in is not the same as $h itself? -- Gaal Yahas <[EMAIL PROTECTED]> http://gaal.livejournal.com/
