/**
 * @assertion E removeAt(int index)
 * Removes the object at position index from the list.
 * This method reduces the length of this by one and moves all later objects
 * down by one position.
 * Returns the removed object.
 * The index must be in the range 0 ≤ index < length.
 * Throws an UnsupportedError if this is a fixed-length list.
 * @description Checks that [UnsupportedError] is thrown
 * since [Float32x4List] is a fixed-size list.
