LDC will soon be able to compile & link some trivial D code 
directly to WebAssembly, without any external tools. Don't expect 
a seamingly simple `writeln()` to work soon though [you don't 
even have access to the console in WebAssembly and must interop 
with a JavaScript function to do so AFAIK].
https://github.com/ldc-developers/ldc/pull/2766#issuecomment-403222908 for how to get started.
