I personally use ClojureScript with type annotations from Plumatic (former Prismatic) Schema and it works really well. Obviously it's not the same as an actual typed language, but it gives me a good-enough starting point to leverage some typing information and perform some rudimentary (runtime) type checking. I also feel it's really nice as some kind of "inline documentation" to be able to see the type of your parameters (obviously this is a given benefit for statically/explicitly typed languages).

I have heard only good things about Schema, and I probably should have invested the time to understand and use it more intensively.

Just dive into it. After wanting to be a bit more descriptive and assertive about the input and output of certain functions in some code I was writing, I must have spent all of half an hour reading documentation and successfully adding Schema to my code. Might be a bit of a rose-tinted memory here in respect to the pastimate :) But it certainly is both easy to understand and use.
