As I mentioned above, it probably varies per person. Nobody has reliable "head data" (studies) either way. If you can donate for a formal study, that would be great. But until then, my experience with other programmers is that people think different from each other. One's own head is not necessarily extrapolate-able to other heads. It's too small a sample size. For my head and a couple of others who have agreed with me, an ordered map is a better root linguistic structure than nested lists. It's more natural to OUR heads. No language will make everyone happy, but map-oriented languages are under-explored. I intend to explore. Call me "Ferdinand Mapgellan".
