Expect While Loops - Partial Automation?

I've been reading the O'Reilley expect book and I'm trying to create partial automation for common questions asked on screen in a telnet session and return to interact so the user can resume control.

For example

Code:

while {1} {
     expect {
        -re "What color is the sky?" {send "blue\n"}
        -re "Should you touch a hot stove?" {send "no\n"}
        -re "DNS Server:" {send "4.2.2.1\n}
        -re "##alias" {send "do stuff\nthen stuff\n"}
         interact + return
        }

Can I have an automatic loop that will let me interact with the telnet session and pick up automation when these key questions are asked and will the alias work if I type ##alias in the interact part of the session?

Thanks
