@AllMonksWhoTookTheTime

Thank you, esp. for explaining what must seem obvious to you by now. (I hope this thread survives: at my age, I'm sure I'll be back to read it... ;^) )

Note @Stevieb: Re: Devel::Examine::Subs had to install a good number of other modules first, so out-of-touch was my CPAN, and now am only failing t/42 and t/43. Clearly, from you own observation, presaging others', about the "uncertainty" associated with retrieved parameters, the pressure to have and use the tool is off. I'll give it a few more good tries, but will otherwise take the hint and move on and look for my answers in the source. Thank you.
