5 - [onleave] command, executing something as soon as the current procedure
6 returns. With no arguments it returns the script set, with one appends
7 the onleave script. There should be a way to reset.
9 Currently we have [local] which can be used to delete procs on proc exit.
10 Also try/on/finally. Is [onleave] really needed?
12 OTHER COMMANDS NOT IN TCL BUT THAT SHOULD BE IN JIM
