Why not just split interpolated string into just a tuple of args 
& strings. For example:
Given: (i"I ate %apples and %bananas totalling %(apples + 
bananas) fruit.")
Is lowered to a tuple: ("I ate ", apples, " and ", bananas," 
totalling ", apples + bananas," fruit.")

It seems current version unnecessarily ties to printf formatting 
syntax, and makes harder for them to be used in custom user code.

Also user still needs call a function to get assembled string 
which differs from what other languages are doing with 
interpolated strings.
