Seems fairly similar to `interp` in scriptlike: 
https://github.com/Abscissa/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 ;-)
