Lets you emit text format of WASM from a Clojure style variation of the WASM sexp syntax. So no, it's not compiling Clojure.
But it's not a Clojure->WASM transpiler/compiler, but Clojure-like->WASM transpiler/compiler, as only a subset of Clojure has been implemented and it's not compiling the standard library of Clojure into WASM.
