Two lines of equations aren't a simple to use programming tool. It's debatable whether TFA achieved that goal, but you certainly didn't.

It's very easy to turn those simply stated equations into a short program that looks quite similar, without lots of strange metaprogramming going on.

As a bonus, others will easily be able to understand and fix or extend the code.

Please show us an example in one language.

I don't see any metaprogramming going on in the original post at all.
