Evan, Very exciting, date manipulation is timely for me, rather than wait I will look into some existing options. *Is there value sharing what I find, or do you have it covered?*
On multidimensional, I am not so much looking for array manipulation. Tiddlywiki and your solution already meets my requirements. Imagin a large 2d spreadsheet with 3 columns containing unique keys (or missing keys) even including date/time. If you choose a key and sort on it before you manipulate a 2D array you are effectively looking at the data in another dimension. This is very easy for TiddlyWiki. *May I ask how you use the results TRUE and FALSE in wikitest once calculated?* Do you use it in filters etc?
