Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What happens in a garbage collection system where only a local variable in the host language has a pointer to an object?
Check out our handle implementation here.
-
Would it be good to add inconsistency to add a small string variant in the value payload?
This is what we did in Skybison and it worked just fine.

The Toit language is now open source
The codebases have very similar naming patterns and structures that mean that once you've read one, the others are much easier to understand. Check out, for example, Dart's VM. Or https://github.com/facebookexperimental/skybison

Faster Python with Guido van Rossum
Guido appears to have meant to refer to Skybison (https://github.com/facebookexperimental/skybison), which is not 100% compatible.

In particular, what was the performance impact of your moving GC? (The documentation for the GC, https://github.com/facebookexperimental/skybison/blob/trunk/doc/garbage-collection.md, appears to be a dead link, is it present somewhere?)

Lisp Badge LE
I love his projects too. He's also the creator of uLisp.

Lisp in Space
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.

-
fe: A tiny, embeddable language implemented in ANSI C
There's also ulisp (for Arduino projects etc.): http://www.ulisp.com/
This is larger, because there are functions for accessing peripherals, and the core is more standard lispy with 'caadr' et.al., and it has a compacting GC, so images can be saved as a compact blob.
- ¿Any interpreted lenguage working in low memory microcontrollers?

Anyone tried to run ECL on a Pi Pico?
You might consider uLisp, it's very Common Lispy for the memory constraints given (sans macros and splicing quote). And you can still connect to it and save an image. I've tried it and it works well enough. Here is the homepage.

What do you think of Forth?
Agreed - the interactivity is good. Lisp is close (have you seen http://www.ulisp.com/ - I can't believe they got into into that small a target!). Python is ok, but for some reason I don't use the REPL in the same way I do in Forth - I think calling functions is just harder somehow. Mostly is exploring valves from the Python REPL.
