Microsoft has already been using this for many years just look at the
win32 api GetMessage function.
LPMSG lpMsg, // message information
HWND hWnd, // handle to window
UINT wMsgFilterMin, // first message
UINT wMsgFilterMax // last message
Seems like it's a boolean return no?
Looking at the documentation reveals that it can return True, (non
zero) False, (zero), but in the case of a failure it returns
-1. Aargh, so maybe Maybe should be defined as -1 ;-)
