I hope some day D gets some WASM story going. Right now the support is very limited, pretty much only through the C subset of D which defeats the point. Supposedly the GC was the main issue, but other GC enabled languages are already thriving in the Web (Go, Java, C#).

There were some efforts to enable D on the web but it seems like these are mostly one man efforts that implement only the minimum features that their specific projects required.
