Lua

Fennel is interesting.

Notes

• Lua was created explicitly to be an embedded scripting language. It's evolution has very tightly focused on that usage, and that continues to be the most common way it is used. It's language as library, a small, pure ANSI C library with no external dependencies. It's easy to include in a project and extend, while remaining a powerful, expressive language that performs well. It's fantastic for that purpose.
• Lua is a language I really want to love. I like the emphasis on simplicity and minimalism, and the Scheme-like semantics, which mix imperative and functional styles, really hits a sweet spot IMO. LuaJIT is a crazy impressive feat of software engineering. However, there are some specific issues which hold Lua back IMO. First, as LuaJIT author Mike Pall famously noted, the Lua authors constantly break compatibility between releases. Lua is really several different, incompatible languages (Lua 5.1, 5.2, etc). LuaJIT is still at Lua 5.1, IIRC. Second, there are a bunch of minor nitpicks (1-based-indexing, anyone?) which turn off a bunch of people. Lastly, because Lua is so minimal and focused on portability, people end up reimplementing their own abstractions (such as object systems) from scratch, further fracturing the ecosystem. I think there's a space for a new project, which takes LuaJIT as a starting point and addresses some of the issues I described. It would also be great if this hypothetical new language had better support for Unicode and concurrency.
