So, my perspective, looks usual and customary.

I do worry about the turing complete nature of testing and the endless lets bury more code into tcl, but, that’s not a problem with the patch.  I don’t have a nice beautiful solution, but, if someone wants to lay out one, we’ll know it when we see it.
