:facepalm:

Thanks!

That is pretty cool. Coupled with a logging function:


     import std.experimental.logger;
     int apples = 5;
     int bananas = 6;
     //equivalent to: alias msg = i"$apples apples and $bananas bananas";
     alias msg = AliasSeq!("%s apples and %s bananas", apples, bananas);
     logf(msg);
     ++apples;
     ++bananas;
     logf(msg);

This works pretty well, shows the filename/line numbers, and reevaluates 
the log message each time.

Another cool use case.
