    Not exactly the same (doesn't embed into the source like this did), but I believe Hylang[0] is the best Lisp package available for modern Python.

    Isn't that a bit what hy (https://hylang.org/) tries to do ? AIUI it is a lisp interacting directly with the AST of Python, allowing seamless interop: Python modules can be used from hy and vice versa, everything is transparent.

    I’ve been keeping loose tabs on this and Hy[1] for a while, but I’ve had some trouble figuring out the major differences between them and the use-cases for either. Would love to see an in-depth comparison in the form of a blog post sometime (though maybe the answer here is to do the research and write one up myself).

    “Python is for scientists. Lisp is for engineers.”

    Then what does that make Hy language?

    Re Languages with lots of example code and LLM’s

    With translators or things like Hy lang, one could get the LLM’s to solve your problem in Python before converting it to another form. Then, you just need a translator. If lacking one, it’s easy to translate by hand.

    The practicality of this concept will probably vary by use case. My experiments had GPT doing sketching, implementations, boilerplate, and even porting Python to Rust. A legally-clear LLM trained on multiple languages could probably be fine-tuned to do Python to LISP conversions. If not, Hy might be a stepping stone, too.

    One of the funny things about Hy is that it's a Lisp for Python, and so one of its primary selling points is that it provides a macro system for Python, but Python is so dynamic that things that would require macros in many other languages can be done entirely at run-time. For example, I define all my monster, scenery, and item types with (defitem …), which could look like a macro call to the casual reader, but is actually just a function call with keyword arguments. One way Hy makes this kind of call more convenient than Python does is that it allows multi-statement anonymous functions, so you don't have to predefine all your callbacks. Here, for example, you can see the method definition for hook-player-walked-into for exits embedded right in the call to deftile.

    You could say so: I've been maintaining the compiler since 2016 ;). Infinitesimal Quest 2 + ε (SQ) exists more to advance Hy than for its own sake.

    A good starting point might be Hy [0]. Its claim to fame is being a LISP embedded in Python.

    I don't think it's nonsensical to use less popular/exotic languages. I prefer to write code in languages that I like to write in, as long as it's a good enough tool for the job.

    The real problem with them is that while you and I might be interested in functional languages, our coworkers/managers aren't and we have to stick with the languages we might not find as immediately exciting, like python.

    Side node, python has Hy (https://hylang.org), which is essentially a lisp implementation that compiles to Python's AST. The entire python ecosystem and stdlib is available to Hy, so it's as batteries included as python is. It's a blast to use, but similarly I wouldn't expect my job to be excited about it.

What are some alternatives?

When comparing Fennel and hy you can also consider the following projects:
