I've been using the Google Closure Compiler for a few years but I haven't played with the actual Closure Library that much.
When I compile my app, I get the following warnings. The referenced code is in the library itself, not in my files. I'm wondering whether I should do something to fix them or just wait for the Closure Library contributors to do that.
/Users/Jan/.../closure-library/closure/goog/dom/dom.js:673:

Nothing breaks as far as I can tell. The warnings do not pop for just one project but I do use the library the same way for all.
