I hazard the opinion that you find many (rudimentary?) examples of
functional programming in spreadsheets (any vendor's). Which are also
very good examples of 'disposable' code a.k.a. 'engineering' code.

Say, the SUM function, which takes a Range of cells to give a total,
without requiring a loop index. Very functional. No?
