The thing that would make a true 'killer app' as compared to Tcl is if it worked
well on Windows and had a model that extended to a more abstract API (not just
character streams, which, IIRC, is central to expect). Given the pty support,
that seems unlikely. Too bad.
Have you used pexpect enough to explain why it's good, or is this an 'in
principle' argument? I agree that expectish functionality would be nice.
Something that I could grow into a Windows/not-just-pty's model would be even nicer.
