To avoid corner cases in auto-generated code?

Sounds like zero-sized types in Rust, where it is used as marker types (eg. this struct own this lifetime). It also can be used to turn a HashMap into a HashSet by storing zero sized value. In Go a struct member of [0]func() (an array of function, with exactly 0 members) is used to make a type uncomparable as func() cannot be compared.
