Barring some better option coming up in the mean time, I will probably end up doing this. At the very least, I'll get more exposure to Parrot's guts this way. Still, I'll also file an RT ticket asking for the general solution under the "twice requested" rule. I'll reference this thread, Paul's old thread, and our IRC conversation in the ticket. -'f
