String Interpolation support in VS Code

[Arredondo]

Coming back to D after a few years of inactivity, and I'm 
pleasantly surprised that we now have string interpolation (sort 
of) in the language.

The issue I'm having is with Visual Studio Code. I'm getting a 
red squiggle under the entire expression with a nonsensical error 
message, when in reality the code is fine and compiling fine.

Here are the D related extensions I have installed:

  - D Programming Language (code-d) by WebFreak
  - d by colinkaopu
  - d-code by tonyjewel
  - C/C++ Extension Pack by Microsoft
  - CodeLLDB by Vadim Chugunov

Has anyone encountered this issue? I'm also open to suggestions 
for other tooling options if there's something better than VS 
Code for D programming in Windows.

Cheers!
Arredondo.
