Unless `module-set!' or `current-module' have been rebound within the lexical environment <env>, the following two forms are equivalent: (module-set! (current-module) 'x 5) (local-eval '(module-set! (current-module) 'x 5) <env>) Therefore, my analysis covers the case you were thinking about as well.
