do you mean to say there's a rust macro that lets you type java in rust? that's a horrible thing to invent! un-invent! exterminate at once!

There is, sort-of, and the macro appears to kill this tool. ;)

Nothing happens, and I see this in the developer console:

  ReferenceError: WebAssembly is not defined

Does this need some kind of special browser?

Are you running the latest firefox? Works for me, but I don't see anything special about it.

I've tried this in Firefox and Chrome both for macOS and Android and it works in all cases.

Yes, I'm using the latest Firefox on my update channel (ESR), namely 52.9.0. It's up to date.

WebAssembly is explicitly disabled on the ESR version of Firefox 52, per https://www.caniuse.com/#search=webassembly, so that would explain that.
