That’s very interesting, but to be perfectly honest it’s almost the exact opposite of how I’d tend to think of things whilst building or manipulating a model. I don’t want to offend anyone, but it feels baroque, like something bolted-on, and it kind of breaks the whole “spreadsheet extruded into arbitrary dimensions” (cube) metaphor.

(Such as how in the accursed Excel, at least up to the last version I was blighted with having to use, one couldn’t take a cell of a Pivot table as the input to another formula elsewhere.)
