FWIW, that is something Adam opposed, but I insisted on. I did 
not think a String Interpolation DIP would be viable without it.

I still feel like one should be able to use an interpolation 
tuple as a string, but it's really hard to come up with a design 
that doesn't feel like a complete hack.

It's indeed much much simpler to just push that requirement to 
build a string if desired on the user.
