There's always Common Lisp using the popular SBCL implementation. It's not statically typed but you still get compiler warnings about types at compile time -- even cooler is that SBCL uses the types for assembly code optimization, so it can also guide you to write faster code with type warnings, e.g. about places where it couldn't infer the type and is forced to use a generic addition.

https://news.ycombinator.com/item?id=14780381 shows a few errors that provide typo protection, no type declaring needed

https://news.ycombinator.com/item?id=13389287 shows the optimization warnings

https://news.ycombinator.com/item?id=12222404 shows it can even delete unused code thanks to type inference

There's also a handful of attempts to bring stricter type checking guarantees on top as a library, but I haven't experimented with those. I'm very much in the crowd that doesn't find static types very valuable (apart from aiding performance) even for multi-million-line projects, but if I can get a few non-strict warnings like SBCL gives, that's a nice bonus, much like running a concurrent linter for extra warnings in <any lang>.

I liked Clojure a lot, but fell out of love once I realized how much it's still missing from the Common Lisp it was inspired from (non-bonkers OOP, condition system, and reader macros being the biggest to me), and also how its pervasive laziness is something I'd rather opt in to than vice versa. Some people feel the same about its immutability-by-default structures, I don't mind either way. (e.g. I can opt in to them in CL, that's fine, and Clojure's ways of opting out of them aren't bad either.)
