This isn’t something you can do, unfortunately. For a workaround, see [templates - Expressions depending on integer type parameters in type definitions in Julia are not allowed - Stack Overflow](https://stackoverflow.com/a/34075704) and [Arithmetic on integer type parameters](https://discourse.julialang.org/t/arithmetic-on-integer-type-parameters/12401)
