Unlike CDLL.__getitem__, LibraryLoader.__getitem__ does use the attribute
cache. Why use a LibraryLoader if you don't want the cached libs and access to
their cached function pointers? That's its main reason for existing. But
really only in Windows, since most DLL names work as a attributes and Windows
LoadLibrary appends .DLL. If you don't want cached libs, don't use a
LibraryLoader. Just use CDLL('msvcr100'), WinDLL('kernel32'), etc. If you want
cached libs without polluting ctypes.cdll or ctypes.windll, just create your
own instance such as windll = ctypes.LibraryLoader(ctypes.WinDLL).
