this code should be valid although it wont be a string but a 
tuple of string & args ready for printing by stdio family of 
printer functions.


Current implementation also requires that a function call to be 
used to get a string, which defies the entire purpose of 
interpolated strings.

It either should be a simple tuple as suggested above (then i 
could live with additional func call to get resulting string), or 
return an interpolated string ready to be used (no additional 
function call).

Alexandru.
