Re: [std-proposals] The Oxford variadic comma

I got the idea, it's essentially writing a template without writing template. I feel super dirty with that one, don't know how that managed to make it in to the standard (specially considering that it can be written in a more explicit way), but that's just the status quo.
I guess there was too much over the keyword auto at the time.

Because this is an abbreviated variadic function template.

If f(auto... x) is a variadic function template, removing x should
result in a function template with the same type. This is the case in
the current draft, it's totally fine, I'm happy with it, and I'm not
deprecating it.
