I think “Pin” is a good example of a technically correct but hard to understand name. “Drop” has a much more familiar meaning because it’s a common action, whereas “pinning” isn’t so common and can mean different things in different contexts. Rather than “pin!(…)”, would “immovable!(…)” be any better? Probably not, and it’s difficult to think of a better one. So maybe a shorthand “colloquial” name doesn’t make sense, and something descriptive like “prevent_moving!(…)” and a PreventMove trait might be better?
