What's even more awesome is that the csh manpage actually refers to
the use of the kill -[signal] syntax:

               or from a command run at completion time:

                   > complete kill 'p/*/`ps | awk \{print\ \$1\}`/'
                   > kill -9 [^D]
                   23113 23377 23380 23406 23429 23529 23530 PID

Hooray for consistency.
