- You can test some of your ideas with respect to Tcl as a safe multimedia
- mail language without resorting to C at all -- if you use "rename" and
- rename a command to "", it is effectively deleted from the interpreter.
-
- It would be nice if your support procs could read and write files and such,
- while procs embedded in mail, or whatever, could only access the restricted
- set.
-
- Dave Herron's multiple interpreter stuff might be just the ticket.
-
- If anyone wants to drop us some mail, we'd be happy to discuss this stuff
- further, or in the newsgroup, or whatever...
