Polynomix

Author's note: I don't think Polynomix is esoteric, although its syntax looks weird. I admit, though, reading the code can be very difficult for beginners.

This article is not detailed enough and needs to be expanded. Please help us by adding some more information.

Polynomix

Designed by	User:I am islptng
Appeared in	2026
Computational class	Turing-complete
Reference implementation	Python
Influenced by	APL SletScript Python
File extension(s)	.plx

Polynomix is a computer language designed by User:I am islptng.
It combines APL's array-oriented programming paradigm with Python's dynamic typing, along with a new design of syntax. There's also inspiration from C++ and Haskell.
