Ahh, ok, I see. (Can't believe they couldn't have just said so on their 
currently-vapid homepage!) If that's the case, then Vibe.D's existing 
HTTP and TCP support is perfectly sufficient, and will probably also 
result in FAR simpler user code due to the lack of necessity for 
callbacks. At least on the server side, anyway. If the client side is 
inside a web browser, then just like ANY language that isn't JS, you'd 
still have have to (directly or indirectly) deal with the fact that 
JS/Webasm is really the ONLY Turing-complete code naively supported by 
modern browsers.

But, unless I'm being overly pessimistic (entirely possible), that does 
suggest a possible important area of improvement for libs such as Spasm: 
a simple no-brainer, common websockets-based API common to both client 
and vibe.d-based server.
