Comment Timing? (Score 1) 46
It otherwise seems like a kind of weird time to do it. In principle what a 'cell' is has never really had an obvious mandatory scale: it has essentially always been relevant that a 'cell' existed in relation to other cells, so that something like an array could be a row; but it has also long been allowed and encouraged to do things like substring operations that acknowledge that cell contents are 'larger' objects that contain smaller ones; and are not automatically spilled out for that reason alone. Not clear that the pragmatic use case for spreadsheets would ever have supported some sort of 'any data type that implies it can be decomposed into elements shall be' rule, strings getting broken up into substrings and so on; but it's also not clear that the pragmatic use case is going to be much clarified by a single cell being n levels deep of lists and arrays of lists and arrays being a fully supported thing rather than something you hack on by shoving JSON into text cells or whatever.
It definitely seems like asking for confusion when some, but only some, "excel spreadsheets" have cells that are arrays, potentially of arrays, while others have rows of cells with contents that, at least formally, are not acknowledged as arrays.
