If the compiler sees that it is moved the whole deallocation
is usually opimized away for the non-exception code path.

It's optimized away for the non-exception code-path if the compiler
sees it.

In C yoU'd have to do the same. And there's only one type of cast
and you could mistakenly cast to a non-fitting type whereas in C++
you've got const_cast<> which may only differ in const-ness.

Array is there to have iterator-debugging on sth. that looks like
a C-array. With C-arrays there's no such feature and it's harder
to find according bugs. If I use static const C-style arrays which
are directed to the DATA-ssegment I always use a span<> on it to
have iterator-debugging, whereas in C you have to take a lot of
care.

C is five to ten times more code for the same task.
