It depends. This example is quite small and a `static if` is sufficient, if you have a lot of cases it would make sense to split thing up into overloaded functions.
Even with a lot of cases you can simply call in each static if a (private) subfunction. I would always prefer this over overloads because it gets you a much cleaner API (I consider the constraint to be part of the function signature, which therefore can get very long and produces a lot of overloads that each only differ in the constraints). Also it becomes more and more obfuscated for which cases there is an overload and for which not.
A good (?!?) example of how bad this can get is the "to" template.
