Aw man I love Expect. We have a bunch of legacy stuff and Tcl/Expect powers most of it. Every few years people try to replace it with python and pexpect, there was a nodejs implementation, and perl. They sorta worked, but anytime you had to something more complicated than a single session or simple parsing they fell apart.

now I have it wrapped in a starpack and just dont tell them the language unless they ask lol
