Now that you mention it, I seem to recall looking at that and not being
happy with the additional dependency on Expect. Expect is *not* a
standard module; on the machines I have handy, the only one in which it
appears in the default Perl installation is macOS. (Huh, what's Apple
doing out ahead of the pack?) I'm pretty sure that Expect also relies on
IO::Pty, so it's a strictly worse dependency than what I've got here.
Can we recast what you did into something like this patch's methods?
