There is something else going on, too, I think. One of the core strengths of Excel is that it frees a lot of people from dependency on &quot;real&quot; programmers.  Any toolset that looks to replace excel (not an easy task) absolutely <i>has</i> to have this feature, or it will be a non-started in many of the core excel niches.<p>However, very few programmers can successfully go into a project that is fundamentally a programming tool, and maintain the mind set of &quot;how I make sure that my own way of looking at this remains completely unnecessary?&quot;<p>If you find yourself having a bunch of conversations with finance types and analysts that all look like: &quot;but if you just approach it <i>this</i> way, it&#x27;s much more powerful because X&quot; you&#x27;ve probably already failed.
