Right fold superpowers!. On a related post,
A function is considered “pure”, if it is [referential transparent (RT)] for all RT arguments, meaning that the arguments passed into a function must be pure themselves. A side-effect, therefore, is anything that violates RT.

You can take a do-file written, say, almost 30 years ago in Stata 3, and as long as that do-file is marked with “version 3” at the top, it can be run, as-is, with no modification, in a modern Stata 16. No broken scripts. No broken programs. No additional effort.

Got a little update to the Macbook yesterday! Three years already, and still as valiant as ever:
The last few days were very, very hot! I don’t remember breathing such hot air in my life. It’s all in the past now, but I’m not about to forget it. A little memory of my last lunch:
We are back with some fresh news from Github: Fast polynomial arithmetic in Haskell.
Switching to Idle for a few days–weather’s too hot, sorry! In the meantime, go check Lisp, the Universe and Everything, and wish me luck with the next Euler problems. Cheers
