Yes, an existing language like shell or lua would presumably be the way to go. The scary aspect of shell is the "Prankster sets up a malicious configuration, asks a sysadmin to help in her repository" scenario. Of course we already have that problem with command aliases, but if the sysadmin has perfect spelling then aliases would never trip, so...

Hopefully that's enough information for anyone interested to start and understand the relevant variables at play.
