That is very reminiscent of Emacs' Org-mode, which has plain text
spreadsheets like the above.  With a key stroke or three a "source code
block", a script written in any of a variety of languages, can be fed
such tables and the results captured in the document as text, table,
plot...

There is a cool org-mode document demonstrating genetic drift using R
plots and a little LaTeX for an equation.  Here it is rendered for the
web.

People use org-mode for everything from literate programming to
reproducible research to organizing their lives (calendars and task
lists).

You speak of morality and then call IF a function.  Blasphemer!

What's a "key word"??

Fun!  Can you do it with coconuts?
