hebigo VS Carp

The Lissp transpiler incrementally compiles and executes each top-level form to Python. It needs to do this in case there's a macro definition that might affect the compilation of a subsequent form. If it's only executing definitions, this is harmless, but if you want to precompile the main module, it needs the guard, or the side effects will happen too.

If you want Python to be as customizable as Lissp, check out Hissp (and Hebigo).

Python's lambdas can have as many lines as you want. Just wrap parens around it. Hissp uses this form as a compilation target. Its REPL shows the Python compilation. Play around with it til you get it: https://github.com/gilch/hissp

The original Lisp's S-expression syntax was just supposed to be an intermediate language used by the compiler when processing the real language based on M-expressions, which kind of never took off. Numerous alternatives to S-expressions have been proposed, and some retain homoiconicity, another feature diagnostic of a Lisp (and one that ECMAScript lacks). For example, see Hebigo's readme, which shows a direct correspondence between its Python-like syntax and that of Hissp's default reader (Lissp), which uses the S-expressions. Julia can also be written in S-expressions, but this usually only used in macro definitions.

I think LoL is too CL-specific. If you know both languages first, you can pretty much translate, but since they'd be trying to learn Lisp in the first place, this is a bad idea.

On the other hand, [Hissp][1] has a pretty good tutorial for anyone coming from a Python background.

Hebigo: a whitespaceLisp isomorphic to Hissp that looks like Python.

Carp - https://github.com/carp-lang/Carp - "A statically typed lisp, without a GC, for real-time applications." where it's "Ownership tracking enables a functional programming style while still using mutation of cache-friendly data structures under the hood".

Looking for a personal project so open-source would be great, but maturity/production readiness is not really a factor.

The only significant thing i can find so far is https://github.com/carp-lang/Carp.

Anything notable that i might have missed ?

Not CL, but there is ulisp (http://www.ulisp.com/) for microcontrollers, supposed to be really tiny, and there is Carp (https://github.com/carp-lang/Carp) which is without a GC so seems suitable for real-time stuff.

by their powers combined

Everybody is trying to make a more user-friendly Rust. The problem is that it is not clear yet whether that's possible, and if it is, how it may look. I know Vale and have tried it, though it's extremely early to judge anything so far. It does have a much stronger theoretical background than V, but even the theory is not completely clear at this point.

There is also Carp by the way: https://github.com/carp-lang/Carp
