Well, Ada has them, albeit in an inconvenient form. You need a
type which inherits from Controlled, and that type must be
declared at library level for some safety reason that Ada folks
appreciate.

I don't know if there's a way to use access discriminants in
combination with generics to get a "universal" cleanup object
that could forward to a function. Ada experts?
