It took me only a couple days of practice to become productive in Tcl and expect (without any "stackoverflow garbage in, AI garbage out!"); it's not so bad.

{ } is like the single quotes in shell except they can be nested.

The basic syntax of the expect instruction is just:

expect {
 { pattern1 } { action1 }
 { pattern2 } { action2 }
 ...
}

-nocase -re means the pattern is a case-insensitive regular expression (as opposed to globbing).

That regular expression has itself nothing specific to Tcl.

Thanks for taking a look!

just to be clear on the commit message: PAUSE will be disabled unless we have a kernel parameter that keeps it enabled. All CI platforms SHALL keep the pause enabled.

That's what I tried to say in the commit message but more briefly and without getting into Intel specifics. Too briefly? I mean, should I change the commit message or is your comment here enough?
