Could This Be the Future for Excel’s Calculation Engine?

Just an outrageous idea I’m mooting…

Ever since Excel burst onto the scene, it’s been based on a worksheet grid. Each cell in that grid accepts either a formula or constant value.

The formula bar is primarily used to input and view formulas (duh!). However, it also does the same thing for constant values.

A cell can only have one or the other, but not both — at least not yet.
