Thanks all for your suggestions. The

const emptystuff = EmptyStuff()

route seems most palatable… except that Stuff in my case is a parametric type with T\<:AbstractFloat. Are there now better alternatives than what is suggested in [https://discourse.julialang.org/t/can-one-make-a-constant-with-a-parametric-type/39444](https://discourse.julialang.org/t/can-one-make-a-constant-with-a-parametric-type/39444) ?
