We're "on the same page," or close to it. I'm creating supplementary tests from in-source-POD, and pure-POD from that same in-source-POD. The main difference between your workflow idea and my current practice is that I haven't separated the POD template out into its own file, à chacun son goût...
I now have some tests asserting that my examples are correct, and pure-POD files alongside the modules. There's a little more to it than that "in real life" but that's the basics.
