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

provided for with a static class function, but one is not provided in this
case - an instance must be created.)
void f()

to communicate back to me. How do I convert a method to an IntPtr?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.

g++-12 -std=c++20 -Wnarrowing bit_field.cpp
