I'm in a situation where I need to embed a scripting language in a Swift codebase and had decided for Wren very recently since some form of coroutines are a necessity for me. I understand Gravity also has Fibers. Would you recommend me to investigate Gravity further? It's a bit unclear what I would get from Gravity that I don't have in Wren. Maybe a slight different syntax?
