Hy is a dialect of the Lisp programming language designed to interact with Python by translating s-expressions into Python's abstract syntax tree (AST). Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte.
This is quite similar to the old GIMP Script Fu that I've worked with in the past. The syntax assumes a join like tabs in HTML, only we'll use parentheses. I haven't studied in detail the implications it has with the python language, but it certainly wasn't invented for nothing.
First, you need to install it with the pip tool.
[mythcat@fedora ~]$ pip3 install hy --user
