If "the above considerations" means the point that I raised, I don't think they would. My point was that that I am accustomed to reading, and writing, backquote constructs with periods -- usually before commas -- and I found this pcase hard to understand given that basis. > Finally, in the example that was brought up, the dot syntax really *was* > used to make comprehension more easy.

I asked about what the valid options for that data would be, but got a nonresponsive reply. -- Dr Richard Stallman (https://stallman.org) Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
