Anecdotally I have to strongly disagree here.

Only one of the tens of heavy users of Excel I have worked with know of this feature on others like it. I am not a heavy use of Excel but my theory is that this is due to a failure of explanation by the software. Excel does not by its design encourage good coding, and most of the users of Excel do not have any programming background so they do not realize that these features should even be there so they wont know to look it up in the manual.

And it's easy to write horrifically bad, but working, code in C or C++. How exactly do you propose Excel butt into your workflow to expose advanced features?

If you plan to use Excel to aid you in making serious money (as countless business do), can't you fork out a thousand extra for an employee who actually knows how to use Excel properly?
