The specific situation where this is particularly relevant is [Resize arrays in mutable structs](https://discourse.julialang.org/t/resize-arrays-in-mutable-structs/49701). If the return value of `resize!` cannot be ignored, then @rdeits [comment](https://discourse.julialang.org/t/resize-arrays-in-mutable-structs/49701/6) is not quite right: you wouldn’t be able to resize a vector contained in a struct that’s not mutable (even though the compiler won’t complain about it)
