It advertises interpreter size and RAM requirements front and center on the homepage, so I assume that's the main draw.

I'm not super familiar with embedded Lua but I believe it to require at least an order of magnitude more RAM and codespace than this, even without float support.

For my money, Berry is still a bit heavy. On a cheap M0 I'd rather have something with about half the required memory.

I did not see that on the front page. Thanks for pointing it out.

My mind shut down about 49 days ago.

Oh, they say it was inspired by Lua. So it's more like Wren I guess, but probably less performant than Wren too[1]. And less powerful than Lua since Lua metatables are half magic half genius. Still, I'd like to see a benchmark like this.

Using Lua for embedded scripting is a delight
