Let's say you're in some function , and you want to accomplish some task x
that is provided for you by a class, A.
Which of these do you prefer, and is there a technical reason for it? (This
is actually the sort of thing that might be
provided for with a static class function, but one is not provided in this

Hi!
I'm trying to use P/Invoke and a Method which takes an IntPtr where I am

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
