How do I create an array in Cpp2 which is on the heap instead of the stack?

[jituderaps]

main: () = {
    p: std::unique_ptr<int> = new<int>[5](1, 2, 3, 4, 5);
}

This happens to work (https://cpp2.godbolt.org/z/8ehdn71W5):

main: () = {
  arr := new<int[]>(2u);
  [[assert: arr[0u] == 0]]
  [[assert: arr[1u] == 0]]
  [[assert: arr[2u] == 0]] // Uh oh...
}

Because #628 (comment) and #628 (comment) aren't implemented yet.
The last access is unchecked because unique_ptr for arrays erases the size.

@hsutter For now, I think you might want the new's T to not be an array type.

This works, somewhat
a := new<std::array<T, N>>();

it terminates on out of bounds access too.

But idk how to initialise the elements

Maybe as addressed at #729.

See #740, and this is now addressed with commit e6a1cc3 .

You can write: pi := new<std::array<int, 5>>(1, 2, 3, 4, 5);
