goog.module is a new way to define Closure namespaces: https://github.com/google/closure-library/wiki/goog.module:-an-ES6-module-like-alternative-to-goog.provide
It is used for example in https://github.com/google/incremental-dom
I didn't do full check of how Closure libraries are handled, but one function which is definitely used by cljs.closure is cljs.js-deps/find-classpath-lib which calls cljs.js-deps/parse-js-ns to read a JS file and parse module information from it. Currently the function reads lines before first function declaration and uses a regex to find goog.provide and goog.require calls. Probably Closure Compiler has some built-in functionality to parse files which could be leveraged.
Besides reading module information from files, another question is if using goog.module defined namespaces for traditional/legacy namespaces generated by ClojureScript compiler needs something special. When goog.module is required, goog.require returns the exported object but no global is set. There is however a function to create the globals: https://github.com/google/closure-library/wiki/goog.module:-an-ES6-module-like-alternative-to-goog.provide#how-do-i-use-a-googmodule-from-a-traditional-closure-file
- Can we still assume that goog.requires all occur before first function declaration?
- Would be fixed by using possible Closure Compiler functionality
