The signature module built its own mapping for static methods. This was a post process after a module was imported. All other mappings worked from alone. Unfortunately, by lazy loading all classes of a module, the final enumeration of all functions comes too early and does no more find anything because the classes and their methods are initialized later. Move this functionality right at the end of InitSignatureStrings. This cleanup is generally a simplification and applicable for earlier versions.
