Ah, that would explain why the presentation from Credit Suisse at
CUFP[1] has that expression in it :-)
/M
I think you're using a somewhat non-standard definition of function.
Say that I have the Haskell expression
let x = 5
y = x + 2
z = x * y
...
Would you call y and z functions? I wouldn't, I would call them
definitions with free variables in the rhs.
But that's beside the point.

that's true and breaks any words that FP thinking is unnatural

Ah...we don't disagree on what a function is, I'm just parsing
spreadsheets
I think Pivotal (http://www.cs.kent.ac.uk/projects/pivotal/) has
the live update behavior of spreadsheets.
I haven't played with it yet, but I saw Keith Hanna show off his
earlier Vital system; it even updates backwards in some sense; see
the Direct manipulation section at his site

You can't define functions in Excel, hence its not really a

There is a Maple plug-in for Excel. If you have Maple (on Windows),
just start Excel and you'll see extra buttons.
This allows you to have cells containing symbols, as well as access to
all of Maple's functions. This easily gets you a (very impure!)
higher-order functional language
The cool thing about Excel is that it's like Function Reactive
Programming. When you update the value of a cell, all the other cells
that reference to it get updated too. That's pretty cool to have in
GUI's as well, and Haskell has that too. See [1].
