I'm sceptical of that. I do basically the same with Bridge.Net 
(with the difference that big part of "services" code is also in 
C#). This isn't a design decision, the architechture is this way 
because spasm didn't exist yet when I started, D was added later.

And I can tell you that interfacing D-borne wasm with Bridge.Net 
is a low of work. D code can't take or pass JavaScript objects 
directly due to how WASM is designed, only their indexes if they 
are positioned in a purpose-built global array. This means that 
if you want to call your D functions in any easily readable way, 
you have to develop an automatic interface template in the ui 
language - introspection capabilites of D will not help. Perhaps 
those can be done in C# or Dart, but sounds unlikely to me that 
it could be done even nearly as well.
