See the difference? In a function, the 'x = x' compiles into LOAD_FAST, STORE_FAST, which only looks at locals and nowhere else. In a classbody, it compiles to LOAD_NAME, STORE_NAME, which looks at locals AND globals -- but still not at closure cells...
Is there a reason why the class body doesn't look at closure cells? That is, are there cases where this lookup scheme is preferred to one that checks locals, closure cells and globals?
