My use case is terminal colours in format patterns, which quickly 
become mental gymnastics and extremely bug prone/easy to get 
wrong. They're largely oneliners, and interpolation would be a 
huge help.

// string logtint, warningtint;
// Exception e;

logger.warningf("IRC Parse Exception: %s%s %s(at 
%1$s%4$s%3$s:%1$s%5$d%3$s)",
     logtint, e.msg, warningtint, e.file, e.line);
