1) Hy (https://hylang.org/, compiles to Python bytecode, usually slower than Python but compatible with all Python libraries)
2) Janet (https://janet-lang.org/, very light Lua-style embeddable VM ~1 Mb, roughly twice as fast as Python for similar ops, very easy C interop)
since we're at it, why not a batteries-included Common Lisp: https://github.com/ciel-lang/ciel it comes as a binary that starts fast and that includes libraries for mundane tasks.

and, we are lucky (or cursed :] ), there are many more cool articles on the topic.
As M-expressions avoid this pitfall, I wonder if any actually language either implemented the homoiconicity and conceptual elegance of Lisp without requiring these encompassing parentheses.
(parens are great though ;) structural editing, no-brainer syntax, easy to extend the language. Once you pop parens, you can't stop)
Though it still has a lot to love for a lisper.
yes, it's exactly what you think it is - here's the whole description, very to-the-point:

really needn't say more.
