cloture VS Carp

For reference, and to show that it's possible, you might be interested in how I did this for Cloture (Clojure in CL): https://github.com/ruricolist/cloture/blob/master/clojure/core.lisp

Why not use something like https://github.com/ruricolist/cloture (a Clojure "adapter" that runs on Common Lisp) if you want that?

Clojure on Common Lisp: https://github.com/ruricolist/cloture

It does not offer the full experience. It has no breakloop and no ability to browse and edit the live running environment. It has no ability to rummage around inside the dynamic environment of a suspended function call, much less to redefine the suspended function or the types of its parameters, nor to restart the suspended call. Indeed, the JVM makes some of that stuff really inconvenient to do.

You cannot do everything from the Clojure repl in the way you can from a Common Lisp repl or from a Smalltalk worksheet.

I don't know that the Clojure language design forbids it; you might, for example, implement Clojure on top of a Lisp or Smalltalk environment and hook up their tools to Clojure through its interop. That might work, and ruricolist has been working on such an implementation called Cloture:

But existing Clojure implementations don't have the full set of tools.

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
