Apple has introduced ARC (Automatic Reference Counting) a long time ago. However, MacVim still mostly uses manual reference counting, which actually introduces bugs like #1164. ARC will not solve everything but should help reduce this class of bugs, and even the lowest required macOS (10.9 at the moment) has long supported it.
