Who Knew?
Today I discovered that C++ standard defines support for using ‘and’ in place of ‘&&’, ‘or’ instead of ‘||’, ‘bitand’ for ‘&’ and a few others. Who knew?
I must say that I’m not particularly sold on the idea - it makes code kinda unreadable. Consider the following code snippets which are equivalent:
if ((num_things and (num_other_things > 0)) or is_one_more_thing)
{
DoBlah();
}
if ((num_things && (num_other_things > 0)) || is_one_more_thing)
{
DoBlah();
}
Personally, I think the second is more readable as the logical operators break up the alphanumeric expressions - the problem could get really bad with complex expressions and highly readable variable names.
But maybe it’s just me…

I agree with you. Also could lead to 'accidental slippage' into reading context in the wrong way.
If one read something like "If FEET and INCHES...", they might assume "and" meant addition. Rather the context might be "if this thing has any size at all, then...
Kind of reminds me of when programmers first discover operator overloading. There's a short period of temptation to coerce the language into some very funky but dangerous behavior! :-)
