You need to remember that perhaps the most important use case for 
string interpolation are string mixins. With DIP1027, one would 
have to write `mixin(i"foreach(i;0..${iterations}) 
foo()".format)` instead of `mixin(i"foreach(i;0..${iterations}) 
foo()")` that works with this proposal. Added `.format` for every 
single interpolated string mixin.

Let's face it, having to import a library function to use 
`printf` with interpolated strings is a small price to pay to 
avoid the first issue.
