There seems to be a fair amount of discussion concerning flow control
enhancements lately. with, do and dowhile, case, etc... So here's my
flow control suggestion. ;-)
It occurred to me (a few weeks ago while trying to find the best way to
form a if-elif-else block, that on a very general level, an 'also'
statement might be useful. So I was wondering what others would think
of it.

Hello all,
I have written a simple whiteboard application. In my application, I
want to be able to set draw attributes. This part works. I have a
dictionary object which contains stuff like:

list so they'll be easily accessed using the function keys. I.e. I have

In Accellerated C++, the author recommends that in a header file one should
not declare
using std::string, using std::vector etc instead one should directly specify
the namespace specifier in code.
for example, this is bad practice:
header.h
#include <string>
using std::string;

Hello,
Can you please help me?
To produce a "&"-sign on the screen, I use "&&". Otherwise I get an
underscore on the screen.
However, when a text is in a database, and I use the same field to reproduce
reports, the name in the report is written also with "&&".
So I want to have it both ways: on screen as well as on paper a single "&"
where a single "&" must be.

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.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
