Oooh -- I totally forgot: for some reason, this doesn't work with 
the wasmer JS runtime. I haven't done any investigation into it, 
since it works just fine with the wasmer Rust runtime.

More work needs to be done before we can fully bring DMD to the 
browser, but this could totally open up the idea of having 
something like Swift Playgrounds within the browser (or perhaps 
some toys like AST inspection, or whatnot).
