In my opinion the only really viable solutions are either to
lower to a function call to format (or similar) such that
typeof(i"") == string or a new type such as Adam describes so
that functions can add overloads for it (and specialized compiler
errors for common misuse cases).
Anything else and you risk users running into inexplicable errors
because their string isn't a string.
