abstract fun removeAt(index: Int): E
Overrides MutableList.removeAt
Removes an element at the specified index from the list.
This method is redeclared as abstract, because it's not implemented in the base class, so it must be always overridden in the concrete mutable collection implementation.
Return the element that has been removed.
