Haha, sorry I ended up changing my mind on stalebot (#3529) but thanks for taking this with some amount of levity 😄. Let's keep this open. This is a bug, I haven't looked into fixing but I suspect it'll require using more of a tokenization approach to detect types involved rather than what's likely a regex here.

[theoriginalbit]

yeah no worries. thanks for re-opening 😄

Same trouble with

let value: Int = 5

Seems it's can be fixed as well as #3438

Same for strings:

static var storyboardName: String = "MyStoryboard"
