According to the tutorial, "if your compiler does not support this, it 
is not a standards-compliant C++ compiler". (I'm only saying what the 
tutorial says; I have no idea if that's correct or not.)

I keep trying to sort out in my head which combination of symbols mean 
bitwise operations and which ones mean logical operations. Using names 
makes the difference clear. (To me anyway.) Of course, none of this 
helps with trying to read other people's code.

(Now Haskell also uses symbols for both. However, in Haskell, if you try 
to perform logical operations on numbers, you get a type error, and vice 
versa. Unfortunately C++ inherits C's braindead "hey, if you can 
represent it as an unstructured bit pattern, it's an int, right?" 
mentallity.)

Uh-huh. Yeah, I'll be doing that. I'd like to write code that will 
compile everywhere. ;-)

Who'd have thought? An M$ product bending the standard slightly...
