Lua is much lighter but the key is that it’s probably one of the easiest things to integrate (just copy the sources/includes and add them to build it’ll work)—like a “header only” kind of vibe.

But, you can strip down a minimal Python build and statically compile it without too much difficulty.

I tend to prefer Tcl because it has what I feel the perfect amount of functionality by default with a relatively small size. Tcl also has the better C APIs of the bunch if you’re working more in C.

Lua is very “pushy” and “poppy” due to its stack-based approach, but that can be fun too if you enjoy programming RPN calculators haha :)
