<kmc> addquote <kmc> i had a dream just now where i was in a gymnasium and they had fire alarm pull stations but they also had a similarly shaped "call/cc alarm" which I think you were supposed to pull if you found a way to write call/cc (it was expected that people in this gymnasium would be doing a lot of programming in total dependently-typed languages)

#!/bin/bash
cd interps
make >& /dev/null &
sleep 20
kill %
wait
echo $?
