--- Comment #6 from Martin Nowak <c...@dawg.eu> --- Should be fairly easy with the new 2-step lookup process (SearchLocalsOnly, SearchImportsOnly), just instrument all symbol searches in expression.d to tag the current scope's func as usesImports, when only the SearchImportsOnly lookup returns a symbol. Furthermore CallExp's using such functions also need to tag their scope's function to make it work transitively. --
