I general, D's approach at this point is to have a solution be in the standard library rather than in the language if it doesn't need to be in the language. And in this case, not only does a template solve the problem quite easily, but it's solving a problem that only rarely needs to be solved these days.

So, while some might prefer a language solution, this really isn't the sort of problem that D is likely to solve in the language at this point.
