// you can use the default %s and custom ones e.g., %.3f

Seems fairly similar to `interp` in scriptlike:

BTW it wouldn't be so hard to add string interpolation to the 
language and compiler, there have been two PRs now. This was the 
latest:

https://github.com/dlang/dmd/pull/7988

I think someone just needs to take a bit of time and write a DIP, 
so that A&W can't say no ;-)
