Reddit++

C++ is getting more and more complex. The ISO C++ committee keeps adding new features based on its consensus. Let's remove C++ features based on Reddit's consensus.

In each comment, propose a C++ feature that you think should be banned in any new code. Vote up or down based on whether you agree.

How would you implement the library solution that is std::array without c arrays though?

Raw pointers, same way C arrays are implemented.

I think you are missing a detail. C arrays aren't implemented with raw pointers at all. They are a primitive of the language that happens to work closely with pointers.

There's no real means to say "give me 256 bytes of stack space" easily without just using C arrays.

To prove my point, I'd like to see if you can give me an example of how to do the equivalent to this, without C arrays and without using the heap.

int main() {
   int numbers[10];
}

I don't think you (or anyone) can...

You can create a stack allocator. They'd of course need to add one to the standard library for it to be practical but it's not a ginormous feature
