Your going way to complicated by actually passing the variadic arguments
to the generator function. If you don't pass the variadic arguments to

If you are agreeing that chain should be pure and it is just

Such changes should be probably integrated Phobos upstream

I've gotten extremely close. The DPaste link that follows

The first template is capable of generating the string for and
