#22Cool, I like these kinds of projects. When it comes to embedding a scripting language in C, there are already some excellent options: Notable ones are Janet, Guile, and Lua. Tcl is also worth considering. My personal favorite is still Janet[0]. Others? [0]: https://janet-lang.org/
Io is nice (Smalltalk/Self-like). A mostly comprehensive list: https://dbohdan.github.io/embedded-scripting-languages/
That list (or any similar list) would be so helpful if it had a health column, something that takes into account number of contributors, time since last commit, number of forks, number of commits, etc. So many projects are effectively dead but it's not obvious at first sight, and it takes 2 or 3 whole minutes to figure out. That seems short but it adds up when evaluating a project, causing people to just go to a well known solution like Lua (and why not? Lua is just fine; in fact it's great).

#23> Uses aliases not pointers, so it's memory-safe How does it deal with use after free? How does it deal with data races? Memory safety can't be solved by just eliminating pointer arithmetic, there's more stuff needed to achieve it
There’s no multithreading so race conditions don’t apply. That simplifies things quite a bit.
There’s actually no ‘free’, but in the (member -> variable data) ontology of Cicada there are indeed a few ways memory can become disused: 1) members can be removed; 2) members can be re-aliased; 3) arrays or lists can be resized. In those conditions the automated/manual collection routines will remove the disused memory, and in no case is there any dangling ‘pointer’ (member or alias) pointing to unallocated memory. Does this answer your question?
I agree that my earlier statement wasn’t quite a complete explanation.
Of course, since it interfaces with C, it’s easy to overwrite memory in the callback functions.

Very cool! I’ve never used Kotlin..

Yes I like this one. It’s similar and even more C-like, in that it discriminates between classes, class instances, functions, methods vs constructors, etc. (Cicada does not).

Yes very C-like.. One immediate difference is that in these C-like scripting languages there’s a split between definitions and executable commands. In Cicada there are only executable commands: definitions are done using a define operator. (That’s because everything is on the heap; Cicada functions don’t have access to the stack). I personally think the latter method makes more sense for command-line interactivity, but that’s a matter of taste.

Seconded.
