Issue description

Using remove_at method of Array throws out of bounds errors even if the size allows for specified index

Using remove_at with negative index:

E 0:00:08:0882   Enemy.gd:163 @ _on_Player_move(): Index p_index = -1 is out of bounds (size() = 3).
  <C++ Source>   ./core/templates/cowdata.h:164 @ remove_at()

Using positive index:

E 0:00:11:0721   Enemy.gd:163 @ _on_Player_move(): Index p_index = 4 is out of bounds (size() = 4).
  <C++ Source>   ./core/templates/cowdata.h:164 @ remove_at()

However, if using Array.erase(Array[-1]) no errors are shown.

Steps to reproduce

if keyboard button is pressed:

var a: Array = []
a.resize(10)
a.fill(1)
a.remove_at(-1)

Minimal reproduction project (MRP)

Hi, for the remove_at() function in the documentation it states that negative indices don't work and that you would need to do arr.remove_at(arr.size() - (i + 1)). Similarly for removing at the size, array indices start counting at 0, so the final index would be a 3 not a 4 for size() = 4.

Hello! As the previous comment suggested, you cannot use negative indexes. It seems like you tried to pop back, i'd suggest you take a look at this method Array.pop_back() -> Variant
